Abstract
6.1 Introduction After having covered the aberration effects, we can go back to the S∕N calculations we performed in Section 2.8.1 for high- and low-temperature applications. We shall analyze several optical configurations and determine the impact of the aberrations for those chosen arrangements. As an additional design example, the Petzval objective from Chapter 3 will be modified to improve its performance by using an aspheric diffractive element. At the end of the chapter, some remarks about instantaneous field of view (IFOV) are presented. 6.2 Basic Assumptions for the High- and Low-Temperature Applications We assume that the field is scanned, using a 45-element linear detector array. Each detector element measures 0.5 mm square. With a spacing of 0.1 mm between each of the elements, the pitch of the array is 0.6 mm. The basic optical system layout with a single lens is shown in Fig. 6.1. With these guideline, we can calculate h ′ =0.5(n−1)δ=13.2mm,andu p =h ′ ∕f≈0.07rad.
