  1. Cone-shaped detectors for superresolution C.F.C.Weststrate, B.M. ter Haar Romenij, M.J. Bastiaans

  2. SUPER-RESOLUTion Super-resolution: measure ‘pixels in between’ The used aperture should be deconvolved Deconvolution is a division in the Fourier domain Instable when zeros in apodization function (standard array) Opname 1

  3. SUPER-RESOLUTion Super-resolution: measure ‘pixels in between’ The used aperture should be deconvolved Deconvolution is a division in the Fourier domain Instable when zeros in apodization function (standard array) Opname 2

  4. SUPER-RESOLUTion Super-resolution: measure ‘pixels in between’ The used aperture should be deconvolved Deconvolution is a division in the Fourier domain Instable when zeros in apodization function (standard array) Opname 3

  5. SUPER-RESOLUTion Super-resolution: measure ‘pixels in between’ The used aperture should be deconvolved Deconvolution is a division in the Fourier domain Instable when zeros in apodization function (standard array) Opname 4  2x zo hoge resolutie in x en y

  6. Biological inspiration: • Why do retinal cones have a cone shape? • Best apodization function • Super-resolution by micro-saccades • Enough light  shape over volume Micro-saccades Model: integral of detector layers. Two physical constructions possible or Light Apodization functionof cone-shaped detector Pit detector Mask

  7. Classical apodization functions

  8. Principle supported by models and simulations

  9. With NIKHEF labs (FOM, Amsterdam) we build a prototype X-ray detector with pit-shaped sensitivity profile

  10. Application areas Visible light: Digital cameras with shake reduction by movable sensor Microscopy super-resolution (piezo X-Y table, optical elements or detector array) X-Ray: Dental X-ray high resolution X-ray crack and welding inspection
