Description

The emitter focal plane module (EFPM) was developed for creating extremely large cost efficient emitter arrays. It is compatible with cryogenic and room temperature environments and substantially increases performance. Its baseline array size is 4x that of existing arrays and provides 20x the pixel power of existing arrays. Its signal data input lines operate at twice the current capability. The EFPM requires an advanced packaging system providing a unique dewar based housing and electronics set. The package proposed here provides all interfaces required by the EFPM. It accommodates benchtop cryogenic testing for better array characterization prior to chamber integration. The package allows easy integration and removal of the EFPM. Further, an internal optical window, added directly to the EFPM, protects the emitter pixels from damage and contamination in all environments. The packages close proximity electronics generate power and clock signals that are distributed to each subarray of the EFPM. The electronics also provide and distribute the very high currents required by the IR emitter pixels. The high current capability is managed in an efficient and array-safe manner. These capabilities and other features offer performance beyond any emitter package previously attempted in the infrared scene projector community. Approved for Public Release 15-MDA-8169 (20 March 15)
