Super resolution infrared camera using single carbon nanotube photodetector

Abstract

Single pixel camera is one of most attractive applications of compressive sensing research, which opens up a new window for image capturing. It will make silicon blind wavelength camera affordable. However, the acquired images are low resolution compared to commercialized single-lens reflex visible camera due to the limited computation and accuracy of compressive sensing. In this work, by analyzing optics of single pixel imaging system, we present a novel design for single pixel camera, which allows for recovering super resolution image by carbon nanotube based infrared photodetector. It samples multiple angular images through different pin holes so that more information is captured. Then, a robust reconstruction algorithm is applied to recover high resolution image. The performance of high resolution single pixel camera can achieve million pixels image from angular images.
