At long measurement distances the receiver signal may remain weak in spite of a laser bias current I increasing far beyond the laser threshold. To avoid laser damage in such cases the maximum current I is limited by a series resistance to about 6/5 of the laser threshold current.

It is to be understood that at least for the short time that it takes, even for long distance targets, for the reference light pulse and the measuring light pulses to be received by the receiving-photodiode 17, the zero-transitions of this exponentially decaying oscillation event are accurately related in time with the exciting light pulse received by the photodiode 17.

Under bright lighting conditions and at great distances, the laser beam output is often inadequate for making the projected point or line visible on the irradiated surface.

At long measurement distances the receiver signal may remain weak in spite of a laser bias current I increasing far beyond the laser threshold. To avoid laser damage in such cases the maximum current I is limited by a series resistance to about 6/5 of the laser threshold current.

These laser distance meters must cover a large usable dynamic range because they must detect very weak measurement light pulses which are backscattered from great distances and from poor targets (e.g., black material) as well as very strong measurement light pulses which are reflected from close range and from reflective surfaces (lacquered surfaces, tile).

Particularly if reflectorless distance measurements are carried out over large distances, the probability that unintended objects between the actual measured object and the instrument will be measured increases.

It is necessary to include a plurality of cast-back light pulses for determining the distance, since, especially in the case of the demanded large distances to natural targets, which are to be determined using the observation device according to the invention, and under the boundary conditions such as eye safety of the measurement radiation, restricted emission power, etc.

Here, the imaging system has the functionality of a telescopic sight, which allows continuous focusing both on objects in the near region, i.e. at a distance from 1 m, and at large distances up to several kilometers.

Solely on the basis of an overview image thus acquired, the reflective markings 64 a, 64 b, 64 c or the reflector 81, for example, at great distances, possibly cannot be identified precisely in position and the measuring laser beam of the tracker therefore cannot be aligned precisely thereon.

This is the case in particular in measurements to target objects at great distances or at a naturally rough surface reflecting with scattering.

With these the vast distances in our country are lessened.

In the case of excessive distances, for example, the environmental burden outweighs the benefit.

This is important in Europe, where distances are long.

In many regions, there are long distances to be travelled.

Airplanes enable people to travel great distances rapidly.

The wind carries seeds for great distances.

And, in addition to the vast distances, there is the harsh climate.

The typical expected distances are about .

Due to its long lifetime in the atmosphere, mercury is transported over large distances.

There may be differences as a result of higher transport distances.

The rail market shows the greatest potential for growth over long distances.

Could have brought him back through great distances, could have brought him back through time.

Freight transport over longer distances in Europe generally means crossing national borders.
