Detection method of performance parameters of laser range finder

Abstract

The invention discloses a method for detecting performance parameters of a laser distance meter. The method comprises steps as follows: the laser distance meter is adjusted to the position where optical signals can be received normally; a multi-way space distance optical waveguide system is provided with multiple first optical waveguides with different calibration distances; the laser distance meter emits impulse type optical signals according to a control command of a control computer and records the emitting time; the optical signals are transmitted to a longitudinal distance shunt comprising a second optical waveguide and a third optical waveguide through a distance meter coupling device, an environment variable simulation system, a shunt and the first optical waveguides; the laser distance meter receives the optical signals transmitted by the second waveguide and the distance meter coupling device and records the first receiving time as well as receives the optical signals transmitted by the third optical waveguide and the distance meter coupling device and records the second receiving time; the control computer calculates the performance parameters of the laser distance meter according to an actual test distance obtained according to the first receiving time and the emitting time, a longitudinal test distance obtained according to the second receiving time and the emitting time as well as default rules.
