Abstract

Disclosed herein are techniques for measuring a reference beam and a corresponding returned beam from a target in a measurement system using a single sensor array. The system is configured such that the location of the reference beam is space apart from the location of the returned beam on the sensor array. A first set of sensor elements on the sensor array corresponding to the reference beam is dynamically activated based on a laser beam scanning control signal. The detection signal from the first set of sensor elements is used to determine a location and/or a pattern of the reference beam, which are then used to estimate a location and/or a pattern of the corresponding returned beam on the same sensor array and dynamically select and activate a second set of sensor elements on the sensor array based on the estimated location and/or pattern of the corresponding returned beam.
