Objectif
This project succeeded in developing a single image intensifier tube in front of a single Charged Coupled (CDI) - also called a single intensifier colour imager for a TV camera - capable of capturing fast-moving objects at 1us and storing the image for processing or analysis.
Television cameras with only 1us exposure time per field for video imaging of fast moving objects without blurring are equipped with pulsed image intensifier tubes as shutters. Up to now such cameras have been available only for black and white pick-ups because image intensifier tubes output screens are always monochromatic and because 3-channel versions for 3 colours (e.g. red, green, blue) would be very expensive.
Electronic shutters are superior to mechanical rotating shutters as they can be triggered by the object. A fast-motion colour camera with only 1 image intensifier and only 1 CCD could become the main component of a low-cost, robust test and measuring system which can precisely pick up the geometry and the colours of fast moving objects, hold them in a frame store or forward the information for automatic image analysis. The basically new step is a high resolution proximity focus image intensifier tube with integrated colour stripe filters coupled to a high resolution CCD by fibre optics.
