Empirical CMOS APS MTF

چکیده
In this work, a unified model, based on a thorough analysis of experimental data, is developed for the overall Modulation Transfer Function (MTF) estimation for CMOS image sensors. The model covers the physical diffusion effect together with the impact of the pixel active area geometrical shape. Comparison of both, our predicted results and the MTF calculated from the Point Spread Function (PSF) measurements of an actual pixel array gives excellent agreement. The results indicate that for any potential active area shape, a reliable estimate of image performance is possible, so the trade off between the conflicting requirements, such as signal-to-noise ratio (SNR) and MTF could be compared per each pixel design.

متن کاملIndustrial X-ray imaging based on scintillators and CMOS APS array: direct X-ray irradiation effects
To see the effects of the direct X-ray in a Lanex screen-coupled CMOS APS imager, we measured modulation transfer function (MTF), noise power spectrum (NPS), and detective quantum efficiency (DQE). These measurements were performed under the condition of non-destructive test (NDT). By increasing the cumulative exposure on the imager, the MTF was degraded, and also leading to the DQE degradation...
متن کاملThe Geometrical Modulation Transfer Function (MTF) - for different pixel active area shapes
In this work we consider the effect of the pixel active area geometrical shape on the modulation transfer function (MTF) of an image sensor. When designing a CMOS Active Pixel Sensor (APS), or a CCD or CID sensor for this matter, the active area of the pixel would have a certain geometrical shape which might not cover the whole pixel area. To improve the device performance, it is important to u...
متن کامل50 μm pixel pitch wafer-scale CMOS active pixel sensor x-ray detector for digital breast tomosynthesis.
Wafer-scale CMOS active pixel sensors (APSs) have been developed recently for x-ray imaging applications. The small pixel pitch and low noise are very promising properties for medical imaging applications such as digital breast tomosynthesis (DBT). In this work, we evaluated experimentally and through modeling the imaging properties of a 50 μm pixel pitch CMOS APS x-ray detector named DynAMITe ...
متن کاملActive Area Shape Influence on the Dark Current of CMOS Imagers
This work presents an empirical dark current model for CMOS Active Pixel Sensors (APS). The model is based on experimental data taken of a 256x256 APS chip fabricated via HP in a standard 0.5μm CMOS technology process. This quantitative model determines the pixel dark current dependence on two contributing factors: the “ideal” dark current determined by the photodiode junction, introduced here ...
