Abstract

A complete intensified television camera has been developed using an intensified CID in conjunction with a standard camera control. The camera has been made in two versions, one for intermediate to low light levels and one for low light levels. In both cases the camera uses proximity focused tubes. The range of the camera has been extended four orders of magnitude with only a 20% loss in maximum resolution over the unintensified version. These intensifiers have been specially modified for use in these cameras. As a result threshold imaging has been achieved at 10^-7 foot candles incident on the faceplate of the tube with the camera operating at standard TV scan rates. The camera head can be kept as small as 3.6 in. x 3.1 in. x 3.0 in. and weigh less than one pound. Selection of the photocathode allows the camera to have sensitivity from the UV to the near IR and allow for fast gating of the camera to less than 5 nsec, if necessary. Both camera designs are discussed with respect to performance and design.
