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