Embodiment Construction
[0029] Such as figure 1 As shown, the present invention provides a high-stability uniform integrating sphere brightness source system based on a galvanometer, including a laser 1, an aperture 2, a polarizer 3, a power stabilizer 4, a galvanometer 5 and an integrating sphere 6 arranged in sequence, The vibrating mirror 5 is connected with a signal generator 10 .
[0030] Laser 1, used to emit laser light. The laser 1 in this embodiment adopts a 532nm laser.
[0031] Aperture 2, used to adjust the beam size.
[0032] The polarizer 3 is used to adjust the polarization direction of the light beam to match the polarization direction of the light beam with the power stabilizer 4 . Wherein, the selection of the polarizer 3 is selected according to the laser 1 and the power stabilizer 4 selected.
[0033] Power stabilizer 4 for stabilizing the light beam.
[0034] The signal generator 10 is used to send a changing control signal to the vibrating mirror 5 to make the vibrating mir...
