Abstract

We report the first computational super-resolution imaging using a camera array at longwave infrared wavelengths combined with the first demonstration of video-rate multicamera integral imaging at these wavelengths. We employ an array of synchronized FLIR Lepton cameras to record video-rate data that enables light-field imaging capabilities, such as 3D imaging and recognition of partially obscured objects, while also providing a four-fold increase in effective pixel count. This approach to high-resolution imaging enables a fundamental reduction in the track length and volume of LWIR imaging systems, while also enabling use of low-cost lens materials.
