hi,
The OPT3101's light source and PD are connected by fiber optics, and an optical attenuator is added to the optical path to ensure that the OPT3101 is not saturated after receiving light. OPT3101 performs crosstalk and phaseoffset (other calibrations are not done, the experiment is done indoors, the indoor temperature changes very little). After calibration, the optical path is added with a known fiber length of 240mm for measurement. The actual measured distance is about 124mm. What is the cause of the measurement inaccuracy?
Thank you！
