AI Technical Summary
Existing methods for correcting the fluctuation in the multiplication factor of photoelectric elements, such as photomultiplier tubes, are inaccurate due to the quantization of pulses with the same wave height but different widths, leading to inaccurate measurements.
The method involves calculating a reference average pulse area based on the pulse area of the photoelectric signal, adjusting the applied voltage to correct fluctuations in the multiplication factor, and using this method to accurately determine the detected light quantity.
This approach allows for precise correction of the multiplication factor fluctuations, ensuring accurate light measurement by adjusting the applied voltage based on pulse area, thereby improving measurement accuracy.
