Light-time camera system for monitoring entire signal path such as for safety-related applications for example safety integrity level, has light-time sensor with receiving pixel and illumination unit for emission of modulated light

摘要

#CMT# #/CMT# The light-time camera system has a light-time sensor (22) with a receiving pixel and an illumination unit for the emission of a modulated light. A modulator (30) is provided for generating a modulation signal which is connected with the light-time sensor and the illumination unit. Another light-time sensor (150) is arranged in the area of the illumination unit such that a part of a light emitted from the illumination unit is received from the latter light-time sensor. #CMT# : #/CMT# An independent claim is included for a method for operating a light-time camera system. #CMT#USE : #/CMT# Light-time camera system for monitoring the entire signal path such as for safety-related applications for example safety integrity level or American society of international law. #CMT#ADVANTAGE : #/CMT# The light-time camera system has a light-time sensor with a receiving pixel and an illumination unit for the emission of a modulated light, where the modulator is provided for generating a modulation signal which is connected with the light-time sensor and the illumination unit, and thus ensures to improve the accuracy of the phase measurement. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a light-time camera system. 22,150 : Light-time sensors 30 : Modulator 40 : Object 140 : Signal receiver 200 : Camera module.
