ELECTRO-OPTICAL
IMAGING SYSTEM PERFORMANCE
SIXTH EDITION by
Gerald C. Holst
The 6th edition focuses on staring arrays. This reference contains all of the material needed to design, analyze, and evaluate the performance of imaging systems with recommended inputs to the current performance model, NVIPM. The 6th edition is divided into six sections: (1) The basics, (2) Imaging system chain analysis: MTF approach, (3) Signal to noise ratio, (4) Targets and backgrounds, (5) Image quality metrics and (6) Acquisition range.
While the main thrust is analyzing infrared systems, the concepts and equations apply to all imaging systems (visible, NIR, SWIR, MWIR, and LWIR). Targets in these bands have different spectral components and nomenclature. Therefore NVIPM contains modules for each spectral band. The detected signal and subsequently displayed image do not contain any sensor spectral information and the post-detector signal is common to all imaging systems.
System analysis is performed in the frequency domain with numerous graphs to complement the equations. Topics include: frequency (MTF) vs. spatial (pixels on target) analysis, two-dimensional vs. two-directional analyses, Fλ/d approach to modeling and system resolution, in-band and out-of-band sampling artifacts, target characterization, atmospheric effects, optics, detectors, displays, sampling, and human perception of image quality.
Probably the most valuable chapter is Chapter 21, Trade studies. The various variables can be considered as slices through a multi-dimensional space. Since it is not possible to illustrate more than three dimensions at any time, each tradeoff analysis represents only one plane through this space. Each tradeoff provides a different view of overall optimization. For example, if a system is detector limited, modifying the optics will have minimal effect on acquisition range.
