Abstract

PURPOSE:To pick up a distance image at a high speed by projecting slit light on the surface of an object body while deflecting and scanning the slit light, forming its optical image on the surface of a shutter through an optical system, and exposing an image pickup surface to the optical image selectively through an opening part in the shutter surface moving simultaneously with slit light scanning and storing the image. CONSTITUTION:A light source 10 emits the slit light R to scan the surface of the body 12 by deflection and the shutter 14 of a TV camera C has a shutter slit 16 at the center part and the image pickup surface 18 behind it. Here, the shutter 14 moves in synchronism with the canning of the slit light R and only when the surface of the body 12 is on an equal distance surface V, the light passes through the light 16 to expose the image pickup surface 18. Then an image of a certain part in a specific distance range on the surface of the three-dimensional body 12, i.e. distance gate image is picked up in real time by making a scan once.
