The DLP Light Commander is a projector that allows for extremely high frame rates, precise control over exposure time, colour balance of monochromatic light, and IR light. It is extremely finicky but very powerful. It runs on 32-bit operating systems only, and has only been tested with Windows XP. There are three different modes for display: Video, where it operates as a normal colour projector at up to 60 Hz; Structured Light, where it displays a series of static, monochromatic images read from onboard memory at rates of up to 5000Hz; and Real Time Structured Light, where it displays monochromatic images from a dynamic input (such as DVI) at up to 1440 Hz. In the software, Structured Light and Real Time Structured Light are differentiated only by source - they are both found under "Structured Light".

The projector has three jacks for analogue triggers that allow for synchronization with cameras or many other devices. The hardware input trigger is located on a pin on a chip somewhere inside the projector but at least one poster on the forum reports that they were unable to find it based on the schematics. The 3 external triggers are for output synchronization.

Loading Images

Images can be loaded via the DLP software application. This requires generating (max) 1024x768 images and loading each one via the GUI. The software will convert these to DBI files. The DBI format is not published, nor is there an external tool to produce these images. However, the software will produce a DBI file from the loaded patterns, and save it to the hard drive. It's apparently fairly straightforward to reverse-engineer this format.
