Abstract
Circuits and methods for generating signals representing the division or multiplication of two analog signals are incorporated into optical triangulation distance measurement systems. In one embodiment one of two analog voltage signals is used to generate a current signal. A capacitor is charged by the current signal. The voltage on the capacitor is compared with the other analog voltage signal and a signal is generated that has a time interval representing the division of the two analog voltage signals. In the application of the circuit and method to optical triangulation distance measurement the time interval signal is further processed to obtain distance measurement to a target.
