This paper reviews and updates the progress in pyroelectric vidicon research and development. The principal items are high readout efficiency for low picture lag, high thermal impedance at the picture element for a high spatial resolution, good target uniformity and cosmetics, low readout noise, and camera design and signal processing.To illustrate the camera potential, a portable camera designed as a fire fighting aid is described.
Although the pyroelectric vidicon infrared sensitive television camera has been available for over a decade, development of the tubes and cameras did not cease with the demonstration of the first imagery.This paper describes firstly the progress which has been made in the UK towards a higher performance vidicon tube, and secondly the improvements to cameras which were necessary in order to obtain the optimum performance from the tubes. Operation of the cameras in a number of situations will be described.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
