Paper Abstract

An intensified linear array instrument has been made by fiberoptically coupling a micro-channel plate proximity focused image intensifier tube to a Reticon RL512S linear photo-diode array. One of the principal advantages of intensification is that the sensitivity of the array can be increased to the photon-counting level. The pixel (p) readout rate is adjustable from 30 kp/s to 300 kp/s, so that rapid data acquisition is possible, and correction for nonuniformities in the instrument response can easily be made by using standard data processing equipment. The measured signal transfer, uniformity, spectral response, MTF and dark current characteristics of this instrument are presented, and alternate instrument designs are discussed. The electronic gating capability of an optional image tube assembly allows optical events as fast as several nanoseconds to be captured. This instrument has been designed in modules so that it can be coupled to a wide variety of existing spectroscopic optical systems. The modular design allows the optical interface flange, the image intensifier tube assembly, and the Reticon array assembly to be easily and quickly changed. It is possible to place the input face of the image intensifier directly in the focal plane of optical systems, such as spectrographs, so that no additional optical elements are required. This versatile instrument can provide more efficient data acquisition of spectroscopic or other linear array optical signals with less distortion than other instruments which do not use microchannel plate proximity focused image intensifiers.
