A discussion is given of certain aspects of hologram recording using computer control. The computer link is sometimes via direct computation of the fringe pattern of the hologram. This paper discusses the more simplistic and pragmatic use of the computer to control the position of a spot of light thus in effect creating images by point-by-point drawing. It is pointed out that the method has distinct advantages over simultaneous (coherent) recording if certain points of detail are attended to. A method is proposed for the recovery of images of large number of sequentially recorded luminous points.
