  • Apparatus and method for detection and demodulation of an intensity-modulated radiation field
    Patent number: 5856667
    Abstract: An imaging sensor (13) has a multiplicity of sensor elements (16). Each sensor 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 store 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.
