An apparatus for providing both day vision simulations and night vision simulations includes a projector that seamlessly provides both night and daytime training modes. The projector includes two independent light sources, with an embedded night vision filter affixed inside the projector proximate one of the light sources to achieve the night training mode. The operator will select one light source according to the mode desired (daytime training mode or nighttime training mode). Each light source may easily be selected, and the light paths from both of the light sources may have a common path when exiting the projector for efficient operation between modes.

L'invention concerne un appareil permettant de fournir des simulations visuelles diurnes et nocturnes et comprenant un projecteur qui engendre en continu des modes d'instruction diurne et nocturne. Ledit projecteur comporte deux sources de lumière indépendantes, avec un filtre de vision nocturne incorporé fixé à l'intérieur du projecteur à proximité d'une des sources de lumières, afin d'obtenir le mode d'instruction nocturne. Un opérateur sélectionne une source de lumière en fonction du mode souhaité (mode d'instruction diurne ou nocturne). Chaque source de lumière peut être facilement sélectionnée et les raies spectrales émanant des sources de lumière peuvent posséder une raie spectrale commune, lorsqu'elles sortent du projecteur en vue d'un fonctionnement efficace entre les modes.
