Abstract
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.
