Small pixel cross-talk MTF and its impact on MWIR sensor performance
TLDR
In this paper cross-talk MTF data has been collected from recent publications and the development for a generic cross- talk MTF model to fit this data is investigated and the impact on sensor performance is included in the sensor performance assessments. Expand

MWIR sensor well fill: sources, effects and mitigation
Detailed radiometric analysis has shown that 3-5 µm medium wave infrared (MWIR) staring array well fill quickly reaches very high percentages, once hot optics, path radiance and inefficient f-numberExpand

Field of view selection for optimal airborne imaging sensor performance
TLDR
We present a trade-off methodology to select the optimal FOV for an imaging sensor that is limited in aperture diameter by mechanical constraints (such as space/volume available and window size) by balancing the influences FOV has on sensitivity and resolution and thereby optimizing the system's performance.

SWIR sensor design considerations
TLDR
With the emergence of Shortwave Infrared (SWIR) InGaAs detector arrays, designers of electro-optical imaging systems can take advantage of the reduced Rayleigh scattering of the SWIR band when compared to visible, resulting in higher contrast images through haze, mist, rain, fog. Expand
MWIR FPA control for optimal NETD
TLDR
The focal plane array in an MWIR camera should be configured optimally in terms of readout mode, stare time and gain setting to achieve the best (minimum) noise levels and/or maximal usable dynamic range under variable environmental conditions. Expand
SWIR sensor "see-spot" modelling and analysis
The reduced Rayleigh scattering of SWIR radiation, when compared to the visible and NIR band, can be exploited to obtain higher contrast images even under challenging atmospheric conditions.Expand
