“…Our analysis shows that the optimum event width found by Boksenberg and Coleman (1979) and Fordham and Hook (1987) occurs when the effects of under sampling have diminished and the loss of the wings of the event outside the window is not yet serious. Frame subtraction in the CCD-IPCS eliminates errors in the background and so the residual cause of centroiding error at the optimum event size is the noise effect described earlier.…”

“…Therefore, there are more resolution elements obtainable from the system than the physical number of pixels which the camera contains; for example, the CCD-IPCS can be configured to have eight times more pixels than its camera-giving over 2500 computed pixels in the dispersion direction. An exposition of this concept applied to line-scan cameras is given by Boksenberg and Coleman (1979) (the IPCS); the extension of the technique to pixelated cameras is explained by Fordham et al (1986) (the CCD-IPCS).…”

“…The Royal Greenwich Observatory operates two photon-counting detectors on La Palma. These are the IPCS-1 (Boksenberg and Coleman 1979) and the CCD-IPCS (Fordham, Bone, and Jordan 1986). An important activity within the program of work at the Observatory is the characterization of these detectors, including investigating problems or features.…”

Photon-counting detectors are important to many areas of astronomy. A new generation, based on microchannel plate intensifiers, is already in use, and so understanding the fundamental problems of image-analysis techniques which are used by both current and new generation devices is necessary. We examine the "pattern noise" problem which causes modulation of the image. We find that it has a number of sources and suggest methods whereby it may be reduced. The problems discussed have applications to all fields (like CCD photometry and astrometry) which employ few-pixel, image-analysis techniques.

“…0.6Hz), which are equal to the diodic quantum efficiencies of the first cathode in the system, they compare unfavourably with analogue devices at high incident illumination levels. In the case of the Mount Stromlo photon counting array (Stapinski et al, 1981) and previous generation system such as the IPCS (Boksenberg et al, 1972) photon counting is achieved by optical detection of an intensified photon event using a TV type device such as a video camera or CCD operated in the line transfer mode. Among other properties, the basic limit is set on photon detection at high incidence rates when a significant proportion of the photons fall on the same pixel within the frame time of the CCD.…”
