The invention belongs to the technical field of
laser performance testing, and particularly relates to an online testing device for performance of a
laser gyroscope reflector. The online testing device is obtained through performing mechanical
processing,
optical processing and chemical
polishing on
microcrystalline glass material with a cube structure. The body is a straight
prism chamber with a
decahedron structure. The bottom surface of the straight
prism is an octagon of which each inner corner is 135 DEG, and the middle part is provided with a central through hole of which the
diameter is 50mm. A spherical surface output mirror, an
anode 1, a chamber translation mirror, a
cathode, a planar output mirror, an
anode 2, a spherical surface total reflection mirror and a blank surface are successively arranged on six side surfaces of the straight
prism. Two sides of the planar output mirror and two sides of the spherical surface output mirror are provided with four light windows. After a power supply is switched on, the online testing device for the performance of the
laser gyroscope reflector starts to operate. An area which extends from the
anode 1 to the anode 2 through the
cathode in the straight prism chamber is a discharging area. A He-Ne laser output with a
wavelength of 632.8nm is generated on the spherical surface output mirror and the planar output mirror, thereby observing performance change condition of the laser
gyroscope reflector in real time.
