The invention relates to a vision system for representing synthetically generated images for the stimulation of night vision appliances, especially in training simulators for driving or flight training, and lighting and observation operations in night vision conditions. Said system comprises an image generator () for generating image signals of a synthetic image, at least one projector () which is fed with the image signals and used to project the image onto at least one projection screen (), and a night vision appliance () for visualizing the projected image. The aim of the invention is to create a technically less complex, cost-effective visual system, whereby the projected image is visualized through the night vision appliance () in an undisturbed manner when the night vision appliance is stimulated correctly. To this end, the at least one projector () comprises a laser source producing a laser projection beam, that radiates an optical wavelength (X) in the non-visible spectral region and within the spectral sensitivity of the night vision appliance (). The image signals are modulated onto the laser source, which is preferably a laser diode. Preferably, a narrow-band interference filter () adapted to the optical wavelength (X) of the laser source is mounted upstream of the night vision appliance ().

Vision system

A system for measuring unevenness formed by grooves and/or long waves in a surface of an object by using a measuring platform. The system moves the object and the measuring platform relative to each other and projects from the measuring platform a light streak that extends in a direction of the movement onto a surface of the object at a fixed projection angle that is tilted relative to a surface normal of the surface. The light streak is reproduced on a planar, position-sensitive photo receiver with a plurality of successive instantaneous exposures of the photo receiver, where the photo receiver is fixedly arranged on the measuring platform with a recording angle that is tilted relative to the fixed projection angle. The system records the surface along the direction of the movement with a plurality of continuous light-streak images and determines a surface profile of the surface along the direction of the movement from deformations in the plurality of the light-streak images.

A device for detecting deformations in the surface of a workpiece includes a light source for illuminating the surface of the workpiece; a detector situated at a fixed predetermined distance from the light source and a displacing arrangement for effecting a relative movement between the workpiece and the light source. The detector comprises a photoreceiver for receiving reflected light from the workpiece and for generating a first output signal having a frequency dependent from the deformation of the workpiece. The photoreceiver is position-sensitive perpendicularly to a direction of the relative movement. A frequency analyzer is operatively connected to the receiver for receiving the first output signal from the photoreceiver and for generating a second output signal when the frequency of the first output signal exceeds a cutoff frequency. There is further provided a deformation indicator operatively connected to the frequency analyzer for receiving the second output signal therefrom and for indicating a deformation in the surface of a workpiece when the second output signal is received.
