The present disclosure includes systems and methods for calibration of an optical sensor package, including setting an initial detection threshold of a detector, gradually increasing a power level of a signal generator that is in communication with a detector to cause a detected power at the detector to exceed the initial detection threshold, storing in a memory a first power level of the signal generator at which the detected power at the detector exceeds the initial detection threshold, and adjusting the initial detection threshold of the detector to an adjusted detection threshold to include a detection buffer amount within the adjusted detection threshold.

Self-calibrating optical detector

An optical detection system includes a first device that has a first light source and a first light detector, and a second device that has a second light source and a second light detector. The first and second devices are configured to turn on and off the first and second light sources periodically based on first and second control signals, respectively. The first and second light sources are configured not to emit light simultaneously. The first and second light sources emit light in wavelength ranges that overlap. The optical detection system further has the characteristic that when the first light source is turned on, a radiant power delivered to the second light detector from the first light source is at least 25 percent of a radiant power delivered to the first light detector from the first light source.
