Embodiment Construction
[0040] Such as figure 1 As shown, the optical power calibration method of the present invention is based on the principle of spatial linear superposition. In the figure, the LED light source 1 is A1 light source, A2 light source, A3 light source, A4 light source, A5 light source, and B light source in a clockwise direction.
[0041] The present invention includes six sets of LED light sources 1 (hereinafter referred to as A1 light source, A2 light source, A3 light source, A4 light source, A5 light source, B light source) with a certain light divergence angle of the same model and supporting program-controlled power source 2, photodiode light power Probe 3, and supporting photocurrent acquisition module 4, standard optical power meter and supporting probe 5, diaphragm.
[0042] Among them, the LED light source 1 and the programmable power source 2 form the light source module of the calibration device, the photodiode optical power probe 3 and the supporting photocurrent acquisi...
