Název v původním jazyce

A method of a non-contact detection of a moving object absolute position by making use of speckle effect and device for implementation of this method

Popis výsledku v původním jazyce

A system for non-contact detection of an absolute position of moving object by making use of the speckle effect comprising an illumination block (2) formed by a light source (22) which operates in the visible, near-infrared or near-ultraviolet region of the spectrum, and an illuminating optical system (21) adjustably fixed into a motor-driven translation system (23) configured to be placed between the moving object (11) and the light source (22), and which is connected to a controlling and evaluating system (4) having a memory for storing speckle field images; an image sensor (5) configured to be placed in a selected plane of observation of the moving object (11) and connected to the said controlling and evaluating system (4); an optical imaging system (6) configured to be located between the image sensor (5) and the moving object (11); a rotary and translation component (12) for calibrating the system for detecting the absolute position of the object (11), and which is connected to the controlling and evaluating system (4), and configured to be coupled to the said moving object (11) during a calibration phase, where the light source (22), the motor-driven translation system (23), the controlling and evaluating system (4) and the rotary and translation component (12) are connected to a power supply (3), and where the essence of the invention is in the fact that the controlling and evaluating system (4) is configured to determine the absolute position of the object (11), in a detection phase, by correlating the speckle field image from the object with a set of images recorded and saved during the calibration phase, one saved image for each possible position of said object (11).
