Abstract : The patent describes a system for adjusting the sensitivity of an array of sensors. A plate of ferroelectric material that is divided into elements by a multiplicity of transparent electrodes is positioned adjacent to the sensor array to permit light to transmit through the elements to corresponding sensors. The ferroelectric elements and the sensors are each connected to a shift register. The output of the sensor array taken from its shift register is fed to a comparator which is also fed by a reference level source. The comparator then feeds the corresponding element in the ferroelectric plate through its shift register.
