  • Circuit for the reading of linear arrays of photodetectors
    Patent number: 5998777
    Abstract: The read circuit can be applied to optomechanical scanning imaging devices. The circuit is designed for the reading of batteries of photodetectors comprising a specified number N of detection channels, each constituted by N.sub.d sensors positioned in the scanning direction, such that each point of an image is successively analyzed by N.sub.d sensors of a channel. The circuit includes a current summation scale, associated with each detection channel, formed by a specified number M of current summation circuits and coupled to the detection channel by means of a voltage-current conversion device. Application to the thermal imaging devices.
