Übersetzung für "Einfallender strahl" in Englisch

The "beam" of the laws is magnified by with a factor of 10 by the drawing prism.

The materials comprising the layers are selected such that a low refractive layer has approximately the same index of refraction as the prism, and the index of refraction of the higher-refractive layer is selected at a value such that a beam incident upon the entrance face 11 of the prism at the Brewster angle strikes a higher-refractive layer at an angle which corresponds to the Brewster angle, which is determined by the index of refraction of the higher-refractive layer and the index of refraction of the prism or of the lower-refractive layer.

A beam 45 inciding upon the area 46 outside the centre axis, at an angle, is on the one hand directly reflected and returned via the non-shaded area, but a beam 47 resulting from diffuse reflection is directed, for instance, into the shaded area and from there to the bottom face of the annular mirror 41 which has its surface 48 facing towards the area 46 provided with a reflecting coating.

In this example, an incoming parallel beam 40 is partly shaded off by an annular mirror 41 so that shaded areas 42, 43 are obtained.

Since the geometrical arrangement of the refracting and reflecting surfaces of the semi-spheres 25, 26 does not change either if there is rotation around the center 30, an incoming beam 27 is reflected back substantially in itself independent of its orientation with respect to the retroreflector 19 .

At any time at which an incident beam is emitted toward a different reflecting surface, the horizontal scanning operation is repeated at a different height level that is proportional to the angles of inclination of each reflecting surface.

Three beam regions are present, namely the incident beam, the overlap of the incident and reflected beam, and the reflected beam.

The systems described there are based on the structure of a Schwarzschild telescope in which an incident beam is imaged in an image plane via a convex and a concave mirror which are arranged concentrically.

The system described in U.S. Pat. No. 4,205,902 consists of the combination of two Schwarzschild telescopes, wherein the second is constructed backwards; here, an incident parallel beam first strikes a concave surface from which it is imaged onto a convex surface, with the result that a virtual image forms behind the convex mirror.

For the beam enlargement, an incident beam is first directed from the convex mirror of a forwards-constructed Schwarzschild telescope onto a concave mirror of this telescope and imaged in a point.

In order to expand a beam, for example, an incident beam of small diameter is guided onto the convex surface of one of the mirrors and directed by this in the means at a right angle onto the surface of the concave parabolic mirror.

Generally, optical deflection devices cause light beams which are incident onto the deflection device at an incident angle different from 0° and 90° with respect to an optical axis of the deflection device to be deflected in a plane defined by the optical axis and the incident direction, for example in such a way that the direction of the deflected light beam also includes the incident angle with the optical axis, so that the incident beam and the emergent beam include twice the incident angle.

In the following, the part or portion of the main ray which is incident on the boundary surface will be referred to as an incident (main) ray, and the part or portion of the main ray having exited the boundary surface will be referred to as an outgoing or exiting (main) ray.

With total internal reflection, a beam falling on a point, perpendicular to the reflection surface at this point, or the surface norm at this point, respectively, and the beam reflected at this point lie in one and the same plane.

Again, using the second embodiment causes the incident beam ES and emergent beam AS to enter and leave the combined fold device from the same side, though here the beams are not parallel.

The described optical path is independent of whether an incident beam is now imaged or an emerging beam is projected.

In this variant the fold device is formed by two reflecting elements 6 and 6 ? set up at a mutual angle such that an incident beam coming from the right in this figure will be reflected back to the right after undergoing multiple reflections.

An incident beam 43 to be “modulated” with a beam axis 45 is guided in a manner analogous to the beam 23 .

The reflected beam is frequency-shifted in relation to the incident beam by a total of ##EQU11##

That's the parallel incident ray.

You have a parallel incident ray.

In addition, the sample rotates about an axis perpendicular to the incident beam.

The arrangement of the cylindrical electrode arrangement of the emittance changing apparatus has been described above as being symmetric with respect to the incident beam.

The incident beam is split into two beam paths which correspond to extremes of zeroth and first order.

Instead, the incident ray is refracted and propagates through the specimen.

This angle between the incident beam and the detector should not be in the region of the regular reflection.

In this case, the incident ray does not necessarily have to be expanded prior to entering the apparatus.

Once the hole is formed, it will serve as blackbody absorbs all the incident beam energy.

Used in combination with an external laser source it creates a precise perpendicular laser plane to the incident beam.
