Miniature lensless computational infrared imager
  DOI :  10.2352/ISSN.2470-1173.2016.12.IMSE-269  Published OnlineFebruary 2016

We describe a lensless computational far-field imager that responds to thermal infrared light (8–14 μm) and comprises a spiral binary phase grating integrated with an 80 × 80-pixel microbolometer array followed by Fourier-domain computational image reconstruction. We believe this is the first hardware demonstration of computational diffractive imaging in thermal infrared.
