A device that detects or responds to incident light by using the electrical effect of individual photons.A plurality of photodetectors is used to detect the light and determine a first three-dimensional position of the interaction....

- In the simple experiment, a converging lens focuses laser light from two pinholes onto two different photodetectors.
