Abstract
An optical system recycles heat from a cooler coupled with an image sensor across a heat transfer element in order to warm and de-ice a window. The optical system may be implemented in high altitude or space vehicles/platforms, regardless of whether manned or unmanned, and the window may be outwardly facing relative to the vehicle/platform so at to allow electromagnetic radiation to pass therethrough onto the image sensor. The optical system enables the reduction of size, weight, and power by recycling heat exhausted from the cooler to warm the window, thus eliminating the need for a separate de-icing system or device for the window.
