Abstract

Electronic high speed camera with an optoelectronic recording system which is used without modification both in the front-light mode and in the backlight mode. The recording system is provided with a plurality of separate semiconductor video sensors (2) and with an optical imaging system comprising a camera objective (3) common to the video sensors (2) and a mirror pyramid (1), the video sensors (2) being arranged in a circle around the mirror pyramid, wherein to each of the video sensors an electronic shutter means is assigned. For the backlight mode, an optical backlight system (5a, 5b) and a plurality of lumped flashlight sources (4a, 4b) arranged in a circle are disposed before the camera objective (3) which sources can be imaged by the optical backlight system (5a, 5b) and the camera objective (3) to in each case one of the mirror surfaces of the mirror pyramid (1). (Fig. 3)
