1. A photodiode-based detection module, the photodiode-based detection module comprising:
at least one photodiode configured to detect light;
a sensitivity damper configured to temporarily reduce the sensitivity of the at least one photodiode, the sensitivity damper comprising a light source whose light is detectable by the at least one photodiode; and
a controller configured to trigger the light source of the sensitivity damper to direct light to the at least one photodiode to reduce a sensitivity of the at least one photodiode to less than a nominal sensitivity threshold.
