The described power for prestoring in the microcontroller-radiant light numerical value or energy-radiant light numerical comparatives table are obtained in the following manner
：
Open diffusing reflection optical gate (5), laser sequentially pass through the first spectroscope (2), the first diaphragm component (3), diffuse reflector (4),
After second spectroscope (7), the 3rd adjustable diaphragm and uniform beam body (9), photo-detector (10) is received decays through said elements
Optical radiation signal is converted to light radiation value and sent to microcontroller by optical radiation signal afterwards, wave filtering circuit (12)；It is micro-
Controller receives the light radiation value corresponding to the multiple test under identical transmission power/energy respectively, and every group of identical transmission power/
After energy test is finished, microprocessor calculates the average photon radiation value of this group；In the manner described above, write in memory successively
Enter different transmission power/energy and average photon radiation value comparison table；Wherein, the determination of the transmission power/energy values passes through
