Cone laser light intensity test device and test method

Abstract

Disclosed are a conical laser intensity testing device and testing method. The conical laser intensity testing device comprises a focus fixing cover, a collimating mirror, an attenuation plate, a scatter plate, an integrating sphere receiver, a power meter probe or energy meter probe and display equipment. The focus fixing cover is arranged on the focal plane of the collimating mirror. The attenuation plate and the scatter plate are sequentially arranged on a light path where reflected light reflected by the collimating mirror is located. The attenuation plate and the scatter plate are sequentially arranged outside and inside the integrating sphere receiver respectively. The power meter probe or energy meter probe is arranged on the side wall of the integrating sphere receiver. The display equipment is connected with the power meter probe or the energy meter probe. The conical laser intensity testing device and testing method are high in testing precision.

Description

technical field [0001] The invention belongs to the field of optics, and relates to a laser light intensity measuring device and a testing method, in particular to a light intensity measuring device and a testing method of a conical laser light path. Background technique [0002] Lasers are widely used in national defense, aerospace, scientific research and other fields. In the laser light path, it is usually necessary to monitor and measure the light intensity information of the laser. At present, the mainstream equipment for testing laser intensity is mainly a power meter (energy meter). [0003] Usually a power meter (energy meter) generally consists of a probe and a display device. When a power meter (energy meter) tests a parallel laser beam, it usually has a high test accuracy, but when it tests a conical laser beam, the test result usually deviates greatly due to the influence of the angle. At present, when testing the cone laser, three methods are usually used: the...

Problems solved by technology

For the first method, the cone-shaped laser is directly injected onto the probe, which is greatly affected by the angle of the incident laser; for the second method, the collimated laser is injected into the probe, and the adjustment is relatively difficult when testing this method. Difficult and time-consuming; for the third method, the laser is directly incident on the integrating sphere receiver, and this method is also greatly affected by the incident laser angle
