ABSTRACT:
A versatile microsecond multiple framing camera generates a switched beam of illumination derived from a laser and switched by an acousto-optic modulator. The illumination is focused on a subject, and illumination from the subject is caused to scan over a predetermined field by a mechanical or electromechanical scanner. Located in the field is an image recording device for recording the illumination directed over the field by the scanner. The image recording device, in one embodiment, includes a vidicon tube, for short term storage, and a video recorder for longer term storage. A video monitor may be driven from the video recorder. The versatility of the camera is exemplified by the ability to vary exposure times or frame rates by adjusting operator controls which drive the acousto-optic modulator and/or the electromechanical scanner. In other embodiments, the vidicon tube and video recorder can be replaced or supplemented by photographic film.
