Procedure for the control of an optical phase arrangement, procedure for the detection of an object by means of that optical phase arrangement and optical system

摘要

The present invention provides a method for controlling an optical phase network and a method for recognizing an object using such a network and an optical system. The method for controlling the optical phase network (102) includes a step of: reading a measurement signal (116), which refers to the intensity distribution and/or wavefront of an optical signal (104) sent from the optical phase network (102); another step of comparing the measurement signal (116) with a reference signal in order to determine the deflection value (120) bewteen the measurement signal (116) and the reference signal;finally by using the deflection value (120), generating a control signal (124) for controlling the optical phase network (102).
