PHASE MODULATING THIN FILM FOR LONG-WAVE INFRARED THERMAL IMAGING

Abstract: provided are systems, methods, and apparatuses for phase modulating thin film for long-wave infrared thermal imaging. in one or more examples, the systems, devices, and methods include forming a first thin film layer of a first metalens of the metalens array and forming a nanostructure in the first thin film layer. in some examples, the systems, devices, and methods include forming at least one thin film layer of a second metalens of the metalens array, integrating the first metalens on a first pixel of a pixel array of the thermal camera, the first metalens being positioned over at least a portion of the first pixel, and integrating the second metalens on a second pixel of the pixel array, the second metalens being positioned over at least a portion of the second pixel.
