Sensing characteristics of an electrostatic recording camera

The electrostatic recording camera can store a large number of pictures and provide for television transmission of these pictures at arbitrary times following optical exposure. This paper describes analytically the operation and performance of an electrostatic recording camera developed especially for use in observation satellites. The device is seen to have comparable signal-to-noise ratio and sensitivity to those characteristics of a vidicon. Camera resolution is also shown to depend mainly on the readout electron beam.
