Abstract:
Disclosed is a first transmitter that transmits a first optical signal towards a target, a plurality of receivers that receive the first optical signal after the first optical signal is reflected by the target and each provides a respective received optical signal, at least one photodetector that receives the received optical signals and provides at least a first electrical signal, and a processor that receives the first electrical signal to compute a position of the target relative to a baseline position based on: a first position of a first receiver of the plurality of receivers, a second position of a second receiver of the plurality of receivers, the first electrical signal. The processor computes a clearance between the target and a component based on a third position of a third receiver, a fourth position of a fourth receiver and a second electrical signal.
