A composite infrared target simulation display system for field testing of infrared (IR) search and track, guidance and general sensory systems. The system includes one or more tileable emitter arrays scalable without systemic size limitation. The emitter arrays are square faced tiles housing power and control electronics to autonomously display a stored infrared test image according to parameters distributed by a control host and a timing signal. A face of the emitter array is divided into regularly spaced pixel positions, each made up of multiple IR emitters operating in differing regions of the IR band to display an image. Multiple emitter array tiles are joined to form a complete system. Each emitter of each pixel position is individually addressable to be individually controllable with respect to emittance state for displaying an image. Multiple images may be sequentially displayed to replicate a simulated target signature in motion.

Multispectral infrared simulation target array

A programmable transformer incorporating windings embedded in a thin film substrate. The windings are flat wire traces embedded into the substrate, primary on one side and secondary on the other. The secondary windings may be planar or different coils spatially arrayed throughout a thickness of the substrate. The secondary winding may include multiple tap points, effectively providing multiple secondary coils referenced to the single primary coil. Each tap point is bridged to a field effect or CMOS transistor path by which a digital controls permit dynamic adjustment of the turns ratio. The final secondary output depends on the activated transistor paths. Multiple secondary outputs from a single secondary coil and a digitally programmable turns ratio are available aspects.

Programmable microtransformer

A compact perforated heat sink having high heat dissipation has a substrate with a multitude of holes and a thermal conductive pathway to conduct heat from a heat source to the substrate. The surface area of the holes is equal to or greater than the surface area of the substrate without the holes.
