Projection system designed for night vision simulations
ABSTRACT Projection systems designed for Night vision simulation are mainly designed with mercury arc lamps or light emitting diodes (LEDs) as light source. There are different advantages and challenges for both types of light sources, and they work for different types of applications. In this paper advantages and challenges for both types of light sources will be discussed, but the main focus will be on LED light source. The main challenge for the LED projectors are the light output, while stable and saturated colors, very long lifetime and dimming are the advantages compared to mercury arc lamps for the visible part of the spectrum. This represents huge benefits in applications where the operation hours are high and downtime or projector failure is not acceptable. Maintenance and calibration can be drastically reduced to give an overall better image quality during the production lifetime, and become especially important factors in multi-channel applications. For the infrared (IR) part of the spectrum dimming and that there is a separate LED for the IR light are the main advantages for the LED projectors. Similar to there being more light in the visible part of the spectrum for lamp based projectors there are also more light in the IR part as well. For night vision simulations it is not only important to know the difference between the different projectors, but also the difference between different night vision goggles and how they work. The resolution, the light amplification, the signal to noise ratio and absorption spectrum are all important properties of the night vision goggles.
