DEVICE AND METHOD FOR THE DETECTION AND DEMODULATION OF AN INTENSITY-MODULATED RADIATION FIELD

摘要

An imaging sensor (13) has a multiplicity of sensor elements (16). Each sens or element (16) has a light-sensitive zone (17) in which radiation is detected as a function of position. A multiplicity of storage cells (21) successively stor e charges detected in the light-sensitive zone (17) of each sensor element (16) in synchronism with a modulation signal which is produced by the radiation source. The imaging sensor (13) simultaneously detects and demodulates intensity-modulated radiation as a function of position. The invention makes it possible to determine a range of parameters for the object (11) being examined, thus ensuring that the object is accurately recorded for rangefinding purposes
