Abstract:
1. A waveband imager, comprising: a substrate, the substrate being transparent to infrared radiation; a bimorph structure anchored to and spaced apart from the substrate by a post to form a gap between the substrate, the bimorph structure comprising an upper layer of material and a lower layer of material, each of which has a different coefficient of thermal expansion; a light source that introduces a propagating visible wavelength into a thickness of the substrate, the propagating visible wavelength angled to generate an evanescent electric field in the gap; where the bimorph structure is configured to absorb infrared radiation and the bimorph structure is further configured to deflect towards the substrate such that the bimorph structure enters the evanescent electric field and a portion of the propagating visible wavelength in the thickness of the substrate tunnels through the gap and is transmitted through the bimorph structure as a converted visible radiation.
