Abstract
The military uses large Infrared (IR) projector arrays to test its detector
arrays. The IR projector generates scenes of moving objects and standing landscapes
for hardware in the loop (HWIL) sensor testing to simulate real world scenarios.
The IR projector is a two-dimensional array of superlattice light-emitting diodes
(SLEDs) with a custom driver IC and FPGA-based control system.
The purpose of this thesis is to document the custom Field Programmable
Gate Array (FPGA) computer architecture that drives the SLEDs. This framework
is able to convert standard PC simulations to the custom SLEDs protocol using
precise timing to control addresses, luminosity, and framing of the SLEDs. The
work described in this paper examines the computer architecture in detail and the
related testing completed on the current 512 x 512 SLEDs system.
