GB/T 26829-2011Indoor method for testing measurement range of pulse laser rangfinders (English PDF)

2.1 Pulsed laser rangefinder

Pulsed laser light source for EDM.

2.2 EDM rangingparameter

Collectively laser rangefinder for maximum range, the minimum distance measurement range and accuracy parameters.

2.3 Maximum range

Pulsed laser rangefinder under ambient conditions and provisions of the target distance can be measured to a predetermined maximum distance.

2.4 Minimum measurement range

Pulsed laser rangefinder measurement range indicates the range.

2.5 Ranging accuracy

To achieve the minimum distance resolution pulse laser rangefinder ranging.

2.6 Fiber extinction ratio test

Fiber-optic analog standard target distance test pulse laser rangefinder extinction ratio parameters, in order to achieve maximum range of detection.

3.1

laser rangefinder under test shall meet the requirements of the optical axis of the consistency of the technical conditions.

Laser rangefinder previously measured 3.2 Setting operating parameters during the test not be changed.

3.3

Test Test personnel should be familiar with the operating characteristics of the laser safety regulations and test laser rangefinder.

Test Method 4

4.1 Maximum Range Test Method

4.1.1 Test principle

Test principle maximum range shown in Figure 1, the detection device receives through the telescope system receives the measured emission of pulsed laser rangefinder

Laser signals through the optical fiber coupler laser signal coupled into the fiber under test extinction ratio, and then by the collimation of the laser emission system is expanded beam collimation,

Finally, after the attenuator attenuation measured return pulse laser rangefinder receiving system. By adjusting the amount of the attenuator can be detected table
