The paper describes the implementation of a Digital Particle Image Velocimeter (in the Particle Tracking mode) using an advanced, ultra-high speed gated, image intensifier, monochrome video camera. The camera was controlled locally by an internal computer chip with which the image capture and analysis software suite could communicate. The software was mounted on a PC and the captured images were stored on a (PC) frame board, which was synchronised with the camera. The camera could be triggered by external events or by keyboard or software prompt. The frame grabber had on-board storage for four frames of 512 by 512 pixels, each having a resolution of 256 grey levels. This allowed the implementation of a flexible and cost effective DPIV system with a wide dynamic range. Examples are given of the use of the system at very low illumination levels and in the presence of flow directional ambiguity associated with gravity wave motion. Phase sampling in a periodic flow is also demonstrated. The image intensifier hardware and control software allowed multiple exposures, of different duration, within the same digital frame. The camera sensitivity could be adjusted to suit different levels of illumination. This feature is shown to allow the capture of DPIV images with embedded time signatures. © 1995 Springer-Verlag.
