Abstract

A method of controlling a pixel (134) of at least one spatial light modulator (114) is disclosed. The spatial light modulator (114) has a matrix of pixels (132). Each pixel (134) can be controlled individually. The method comprises the steps of: receiving (342) at least one image (331); b) defining (344) at least one image segment (333) within the image (331); c) assigning (348) at least one gray scale value For each image segment (333); d) assigning (350) at least one of the pixel matrix (132) to each image segment (333); e) assigning (352) a unique modulation frequency to the at least one pixel assigned to (134) each grayscale value; f) controlling (354) the pixel matrix (132) assigned to at least one image segment (333) with a unique modulation frequency (333) assigned to the respective image segment (333) ) of at least one pixel (134).

Description

technical field [0001] The present invention is based on US Provisional Application No. 61 / 867,180 of August 19, 2013 as e.g. , 61 / 906,430 of November 20, 2013 and 61 / 914,402 of December 11, 2013 and unpublished German Patent Application No. 10 2014 006 279.1 of March 6, 2014, European Patent Application of June 10, 2014 The general idea of ​​an optical detector as presented in Patent Application No. 14171759.5, International Patent Application No. PCT / EP2014 / 067466, August 15, 2014, US Patent Application No. 14 / 460,540, August 15, 2014, all of which The entire contents are incorporated herein by reference. [0002] The invention relates to a method of controlling the pixels of at least one spatial light modulator, an optical detection method, in particular for determining the position of at least one object, a modulator device, a modulator assembly, an optical detection Detector and detector systems. The invention further relates to various uses of human-machine interfaces...
