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).
