PCT No. PCT/DE97/00681 Sec. 371 Date Sep. 25, 1998 Sec. 102(e) Date Sep. 25, 1998 PCT Filed Mar. 25, 1997 PCT Pub. No. WO97/36193 PCT Pub. Date Oct. 2, 1997The invention is directed to an optoelectronic imaging system for industrial applications having at least two optical lenses (1, 2) which are spaced apart from one another and an electronic image sensor (8), wherein the imaging sharpness on the image sensor (8) and the imaging scale (zoom) are mechanically adjustable by means of a control unit. According to the invention, the at least two lenses are constructed as flexible lenses (1) whose surface curvature can be changed in a controlled and reversible manner by application of externally initiated mechanical force (actuating means 15) and are arranged so as to be fixed against displacement relative to one another in the direction of the optical axis, the image sensor (8) is connected by signal links with a data processing device (14) which is, in turn, connected by signal links with the actuating means (15) of the flexible lenses (1) and delivers signals for an autofocussing function, the data processing device (14) has a storage device in which are stored values for the adjustment of the actuating means (15) for changing the focal lengths of the flexible lenses (1) for purposes of the zoom function, and the flexible lenses (1), together with the actuating means (15), image sensor (8) and data processing device (14), form a compact device unit (16). |
