Übersetzung für "Spectral overlap" in Deutsch

Due to the minimal spectral overlap of the absorption band of the deprotonated chromophore and the emission band of the luminophore, the nonradiative energy transfer rate from luminophore to chromophore reaches a minimum.

Due to the maximal spectral overlap of the absorption band of the deprotonated chromophore and the emission band of the luminophore the nonradiative energy transfer rate from luminophore to chromophore reaches a maximum.

It is more difficult to efficiently generate red since the spectral overlap of the absorption of the red dyes with the blue emission is generally very small.

The optical microprobe according to claim 2, wherein the at least two partially reflecting filters are formed as special color filters for generating the spectrally separated measurement light bundles and the reference light bundles (M 1, M 2, R 1, R 2), and wherein a light source generates the light bundle with spectrally separated spectral ranges for generating the measurement light bundles (M 1, M 2) and the reference light bundles (R 1, R 2) with no spectral overlap.

The optical microprobe according to claim 2, wherein the at least two partially reflecting filters are formed as interference filters with such a cut-off filter characteristic that the measurement light bundles and the reference light bundles (M 1, M 2, R 1, R 2) have no spectral overlap.

By “joint wavelength/joint emission” it is to be understood here that there occurs a spectral overlap of the emission spectra of the at least one joint emission or at least a very near emission (e.g. directly adjacent), so that the emissions appear as a joint emission, i.e. cannot be mutually discriminated significantly, using sensors with a resolution of >50 nm, in particular >10 nm.

In an alternative variant (RR concept) of the method according to the invention, sensor fibers having two fiber Bragg gratings that are arranged in a row and have different Bragg wavelengths are used at two sensor positions that are spaced apart from one another in the rail direction, the shear stress difference signal being generated optically by a spectral overlap of the reflection peaks of the two fiber Bragg gratings during the transition from an unloaded state to a loaded state.

Due to the maximal spectral overlap of the absorption band of the deprotonated chromophore and the emission band of the luminophore, the nonradiative energy transfer rate from luminophore (donor, donor dye) to chromophore (acceptor, acceptor dye) reaches a maximum.

The apparatuses known from the existing art provide for division into the individual spectral regions only in the closer vicinity of the focus line, where selection of the spectral regions to be detected is still tolerable in terms of spectral overlap.

With the apparatus according to the present invention, it is possible to perform spectral selection with the aid of reflective and/or refractive optical components directly in the focal line, so that the aforementioned spectral overlap, which occurs even in the close vicinity of the focal line, can advantageously be avoided.

The spectral overlap with existing services such as broadcasting, maritime or aviation radio and amateur radio is unavoidable, so that without special measures EMV problems are not able to be excluded.

The shortwave laser mode will then correlate with the drop in reflectivity on the long wave side of the reflector stop band while there is no spectral overlap between the long wave laser mode and the high reflectivity in the stop band so that it can hardly oscillate into laser action.

In particular it is possible to also measure spectrally overlapping bands with the device according to the invention.

It is advantageous if, according to the inventive method, overlapping spectral bands can be masked out or omitted, and are thus, not displayed more than once on a visual display unit, or printed out as a so-called hard copy, and the amount of data in a common data set can thus also be reduced.

The object is accomplished by the fact that in a Q-switched semiconductor laser of the kind referred to above the two optically coupled resonators for laser mode selection are provided with differently structured mode combs which overlap spectrally such that at least one defined laser wavelength is selected, that at least one resonator reflector of the two optically coupled resonators is structured as a reflector with a strongly dispersive reflection characteristic in the range of the wavelength selected by the two optically coupled resonators, that means is provided for electrically or optically tuning the refractive index of the dispersive reflector and/or of the passive resonator so that spectral control of the laser mode is accomplished relative to the dispersive reflector.

In respect of the function of the Q-switched semiconductor laser in accordance with the invention, the presence of two optically coupled resonators having two mode combs which spectrally overlap such that a defined laser wavelength is selected—similar to the Nonius principle known from mechanics—is critical for the reason that laser emission would, because of the many possible modes in a simple semiconductor laser, not otherwise be supported by the desired mode.

In order to avoid spectral overlapping in the subsequent discrete-time signal processing operation, each signal is submitted to band limitation in an associated filter 4.

In this way spectral overlaps during this preselection of the signals, and hence in the best possible manner, an overloading of the receiver as well as the "aliasing" effect (scanning frequency lower than twice the highest signal frequency) in the digital signal processing section, are avoided.

Too small an amount of oxidising agent induces the formation of yellow by-products which absorb at 450 nm, whereas the normal amount of oxidising agent, in particular an excess of oxidising agent, decomposes the product (absorption of the product at 353 nm) to by-products which absorb in a spectral range that overlaps with the range of the educt (maximum at 280 nm).

However, there is no need for the geometrical light beam changes by element 38 and the lateral arrangement of absorber surface 37 with respect to the light beam, if it is ensured that the measuring gas in cell 68 and the absorber surface 37 absorb light in preferably non-overlapping spectral regions and the monochromator elements 36, 36' are correspondingly chosen.

This can be made possible by selecting the spectral transmission range of filter 31', or by introducing a suitable gas into photoacoustic cell 41' which does not occur in the measuring gas and which does not have any overlapping spectral bands with the latter.

A new background correction method and an improved spectral correction of interferences allow simple and automatic correction of complex structured spectral background and overlapping matrix lines.

The two information channels now preferably overlapping spectrally are radiated via in-house antennas 13 a, 13 b into a highly dispersive indoor area 14 of a building or of a cabin.

In this manner the sensitivity of the method may, for example, be specifically varied in that the illumination spectrum and the spectral sensitivity of the optoelectronic sensor are displaced synchronously or in the opposite direction of larger or smaller wavelengths (for example, the illumination spectrum may be specifically varied by activation of the current in the opposite direction of multiple spectrally overlapping light diodes).

The partially reflecting filters are preferably formed as interference filters with a sharp cut-off filter characteristic for generating measurement light bundles and reference light bundles with no spectral overlapping.

In an alternative embodiment, they can also be formed as special color filters for generating spectrally separated measurement light bundles and reference light bundles, wherein, owing to a reduced steepness of the cut-off filter characteristic of the color filters, the light source has spectrally separated spectral ranges for generating measurement light bundles and reference light bundles with no spectral overlapping.

Furthermore while forming the third and fourth sum signals, the spectral values of overlapping time windows with (k) samples of the first (L?) and second (R?) sum signals are each dynamically corrected.

Here, the absorption and emission bands of the fluorescent agent used for the fluorescent layer 112 overlap spectrally only partially and preferably not at all.

However, the efficiency decreases when a plurality of dyes with a plurality of wavelengths are excited simultaneously (multi-fluorescence microscopy), since a spectral overlapping of the excitation light and the emitted light usually occurs.

The stack of dielectric layers in one embodiment is arranged in such a way that, in one limited spectral region, which overlaps at least partially with the emission spectrum of the light produced in the light-emitting organic layer, there is a high reflection power (>90%), where a reflection power of >99% can be formed with several layers.

Traditionally, when testing mobile telephones, a transmission frequency response is often determined through a series of generally gap-free or overlapping spectral transformations, of which the spectrum is averaged at the input and output of the transmission path over the duration of the test signal.
