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 (17) for generating image signals of a synthetic image, at least one projector (16) which is fed with the image signals and used to project the image onto at least one projection screen (11), and a night vision appliance (15) for visualising the projected image. The aim of the invention is to create a technically less complex, cost-effective visual system, whereby the projected image is visualised through the night vision appliance (15) in an undisturbed manner when the night vision appliance is stimulated correctly. To this end, the at least one projector (16) 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 (15). The image signals are modulated onto the laser source, which is preferably a laser diode. Preferably, a narrow-band interference filter (19) adapted to the optical wavelength (X) of the laser source is mounted upstream of the night vision appliance (15).
