1 October 2007 Imaging system performance based upon Fλ/d
Author Affiliations +
Imaging system performance can be described in the spatial domain, where the optical blur diameter is compared to the detector size, or in the frequency domain [modular transfer function (MTF) approach], where the optics cutoff is compared to the detector cutoff. Both comparisons provide a metric that is a function of Fλ/d, where F is the focal ratio, λ is the wavelength, and d is the detector size. Fλ/d is applied to three models: Schade's equivalent resolution (visible systems), Snyder's MTFA (MTF area; visible systems), and target acquisition (NVThermIP—an infrared system model). All models produced curves that exhibit a transition in the region 0.41
