“…The transmission efficiency of real lenses is somewhat lower due to reflections at interfaces and vignetting. By integrating a Lambertian input over the diameter of a lens with 'f' number (the focal length divided by the aperture diameter) f, the fraction of the light subtended by the lens can be calculated (Reynolds, 1970;Gruner, 1989):…”

The detective quantum efficiency (DQE) characterizes the measurement uncertainty introduced by a detector. A formulation of the DQE for CCD and vidicon‐based X‐ray integrating detectors is developed and illustrated with five model detectors. A comparison of the calculated and measured DQEs for two of these detectors is presented. From an examination of the DQEs for the model detectors, generalizations are made regarding detector designs.

“…Many attempts have been made to develop electronic area detectors which register the positions of arriving quanta with good detection efficiency. They include multiwire spark or proportional chambers (Cowan, Macintyre & Thomas, 1966;Charpak, Bouclier, Bressani, Favier & Zupan6i6, 1968;Borkowski & Kopp, 1970Kau£man, Perez-Mendez, Sperinde & Stoker, 1971;Xuong, 1972), arrays of semiconductor detectors (Thomas et al, 1969) or of channel multipliers (Gott, Parks & Pounds, 1970) and television pickup tubes (Arndt & Ambrose, 1968;Reynolds, 1970;Arndt & Gilmore, 1970;Kinsey & Reynolds, 1972;Arndt, Gilmore & Boutle, 1972;Abrahamsson, 1972). * Present address: Engineering Research Institute, Faculty of Engineering, University of Tokyo, Bunkyo-ku, Tokyo 113, Japan.…”

An X‐ray television camera using a phosphor screen coupled to an image orthicon tube was prepared to detect and record diffraction patterns rapidly. It is about 750 times more sensitive than photographic film, producing a video signal of S/N = 10 for incident 4 × 104 Cu Kα quanta sec−1 mm−2, and has a dynamic range of 1:30 and a spatial resolution of 6.4 Lp mm−1. The detector system was tested by recording rotation patterns from a single‐crystal of diformylhydrazine, where it was demonstrated that one can measure reflection intensities with an accuracy better than 10%. To process the TV picture by computer, an image readout device using a storage tube was built. The high sensitivity and the large detection window (42 mm in diameter) of the camera and the fast speed (40 μs for each 80 × 80 μm resolution element) of the readout device make the incorporated system most appropriate for rapid measurement of simultaneous reflexions from macromolecular crystals. The camera can also record small‐angle diffraction patterns from muscle in an exposure time of a few seconds.
