An increase in temperature of cascaded image-intensifier tubes increases the photocathode dark emission and decreases the modulation transfer function. The MTF of a cascaded image-intensifier tube has been experimentally measured at different ambient temperatures and the change in the MTF has been correlated with the change in the dark emission.
