Abstract: The invention relates to a holographic information display for a motor vehicle for projecting a virtual display element. A data processing device provides a hologram for the virtual display element to be projected. A control device in each case emits an individual control signal for a plurality of segments of the hologram. A plurality of optical phase delay cells which can be individually adjusted by the control device and are arranged on a face illuminated by the light beam, delay the fraction of the light beam incident thereon in each case in the phase in response to the respective individual control signal.

Abstract: An automated opto-electronic test system for quality control of two-dimensional elements with high geometric figure density, such as printed circuits, intermediate printed circuit products, and printing tools has a semiconductor image sensor disposed above a compound table having a position sensor which moves the test specimen beneath a lens in a meandering path at a velocity which is known relative to the semiconductor image sensor. The signals from the image sensor are first analyzed in an analog signal pre-precessor to which are connected a number of error recognition circuits operating in parallel each of which produces an error report which is transmitted to an error coordinating circuit.
