Web12 sept. 2011 · The MTF of all sensors at 550 nm is similar, but at longer wavelengths, the MTF of a sensor can be lower compared to other sensors. For some sensors, for instance, the MTF is reduced by a factor of 2 or 3 at 850 nm. The amount of MTF reduction strongly depends on sensor technology:

WebResults: When used with a high-resolution converter layer and sensor elements one quarter the size of image pixels, the MTF is increased by 53% and the DQE by a factor of 2.3× at the image sampling cut-off frequency. Both simulated and demonstration images show improved detectability of high-frequency content and removal of aliasing artifacts. WebWhen one system forms an image produced by another, the MTF’s can, under certain conditions, be multiplied together to obtain the overall MTF.
