Abstract

Infrared imaging remains one of the most widely used imaging modalities outside the visible spectrum. The longer wavelength of light in the infrared band reduces scattering in many media and hence allows deeper imaging in a wide range of applications, from optical tomography to deep space imaging. In addition, most molecules have vibrational spectrum in the infrared band that enable many powerful techniques, such as remote sensing and hyperspectral imaging. Lastly, the peak blackbody radiation of objects near room temperature is in this spectral band. Despite such high demands, infrared imagers remain the performance bottleneck in many critical applications. We present our novel devices that can address some of the inherent limitations of the existing infrared imagers, including enhanced sensitivity, speed, pixel resolution, and flexible and curved sensor array. In particular, our new results from bio-inspired nano-injection detectors show significantly higher sensitivity compared with best existing infrared devices, while in parallel they can produce imagers with very high pixel resolution and frame rates. We will also present our novel flexible infrared imager concept, as well as the new results
