Paper Abstract

An imaging test bed has been constructed for exploring the design considerations for selecting the appropriate image sampling or Q for electro-optical earth imaging systems where Q is defined as (λf/#) / pixel pitch. The test bed includes errors such as image smear and shot noise produced by atmospheric haze. The value of Q can be varied by either changing the focal length of the imaging system or by varying the imaging aperture diameter. All of these parameters are varied to understand the effects on image quality. In this paper we explore practical design considerations for selecting Q for an electro-optical earth imaging system. In particular we will focus on image degradation caused by increasing Q by reducing the imaging aperture diameter.
