Paper Abstract

The general characteristics of an electronic camera used in the analysis of high speed photonic phenomena and consequently those of an automatic image acquisition and processing system built around these cameras can be divided into two categories : - The first covers the characteristics specific to the image converter tube used, such as the size and spectral response of the photocathode, its spatial and temporal resolutions, dynamic geometric distorsion, cut-off ratio, etc. - The second are those related to the performance of the electronic control circuits : . sweep ramp linearity, . triggering delay and jitter, . sweep times, . transients that occur while the tube's internal voltages are established during aperture control, etc. The major criteria for evaluating a tube with respect to dynamic operation, which by itself is of interest to the user, will be presented during a brief review of theory. The effect on the quality of the image obtained in terms of the duration and number of Nyquist points in the time analysis window, the resulting Bandwith, spatial resolution and cross-talk will also be shown. These criteria can also be used to determine the improvements in the performance of the TSN 506 camera and the NORMA system obtained by using RTC P 510 and ITT F 4157 image converter tubes. We shall conclude with a brief review of tubes currently being developed, their proven and expected characteristics and their impact on the development of electronic cameras and automatic photon measuring systems.
