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

摘要

The invention concerns an imaging sensor (13) consisting of a multiplicity of sensor elements (16). Each sensor element (16) has a light-sensitive zone (17) in which the radiation is detected as a function of its position. Associated with each sensor element (16) are a multiplicity of storage cells (21) in which the charges detected in the light-sensitive zone (17) of each sensor element (16) are successively stored. The imaging sensor (13) can thus simultaneously detect and demodulate intensity-modulated radiation as a function of its position. The invention makes it possible to determine a range of parameters for the object being examined, thus ensuring that the object is accurately recorded for rangefinding purposes.
