Mature application has been obtained in light-exposed display field, that is, is directed to the visible light of the identifiable 380nm-780nm wave band of human eye.It is right
Infrared light region more than the sightless 780nm wavelength of human eye, occurs mainly with night environment, in the environment there is
Some demands visual for infrared light, such as in military combat, there is no application.In order to improve the utilization rate of DMD, expand simultaneously
Optical projection system can be applied in night simulation, thus need the base in existing optical projection system by the application field of optical projection system
On plinth, increase the function of infrared display.From the point of view of whole optical projection system, infrared light supply need to only be increased by increasing infrared display function,
It is utilized above in the period of a piece of DMD free time.In fact, the difficult point of the program is control section, removed because increasing
IR (Infrared, infrared) light except RGB visible light needs the signal of corresponding IR light to be handled, this with it is existing visible
The control program of light projection system is very different.
