PCT No. PCT/DE88/00075 Sec. 371 Date Oct. 16, 1989 Sec. 102(e) Date Oct. 16, 1989 PCT Filed Feb. 16, 1988 PCT Pub. No. WO88/06325 PCT Pub. Date Aug. 25, 1988.A device for optically scanning an object includes a nozzle which is connected to a source of pressurized liquid. The nozzle generates a liquid stream which can be directed at the object. The device further includes a laser which is arranged to direct a beam of light at the object in order to scan the latter, and a sensor for receiving and analyzing light reflected from the object. The laser and the nozzle are positioned relative to one another in such a manner that light reflected from the object enters the liquid stream which then conducts the reflected light to the nozzle. The nozzle is connected to the sensor by at least one optical fiber which functions to conduct the reflected light from the nozzle to the sensor. One or more additional optical fibers may be provided to conduct light from the laser to the nozzle. The liquid stream then serves not only to conduct reflected light from the object to the nozzle but also to conduct the light used for scanning from the nozzle to the object.
