SDI-2 Holographic Head-up Display System

SDI- 2 model holographic head-up display system can be used for many types of aircrafts, such as fighters, attacker and bombers. It receives data from mission system via bus(422,429,1553B and etc.) and generates images with symbologies. It collimates and displays these images with symbologies of flight, navigation, combat to infinite up front of pilot, which superimposed with outside sceneries to make pilot observe outside and flight & combat information simultaneously.

Primary Functions

1.To connect with external mission system to implement bus communication;

2.To generate symbologies and superimpose with videos;

3.To collimate and display images with Symbologies;

4.To display videos in raster mode;

5.BIT.
