Abstract
A digitally filtered laser receiver includes a plurality of radiation sensors spacially arranged in a manner which identifies a relative position of the sensors with respect to a rotating laser radiation source. The digitally filtered laser receiver includes a microcomputer having inputs which are responsive to impingement of the sensors by radiation. The microcomputer is programmed to process data from the inputs only when the radiation sensors are impinged by radiation from the rotating laser radiation source. The microcomputer processes the data and provides an output which is indicative of the position of the rotating laser radiation source and the sensors.
