Abstract
The present disclosure generally relates to laser range finders. In one embodiment, a shallow-trench isolation diode operates in a reverse-biased mode. In another embodiment, a poly-defined diode operates in a forward-biased mode. In both embodiments, the diode emits photons in response to a radio frequency current, and the photons are received by an avalanche photo diode during a calibration process.
