Introduction to Infrared and Electro-optical SystemsA complete and up-to-date introduction to the analysis and design of infrared and electro-optical (EO) imaging systems. The text details the principles and components of the Linear Shift-Invariant (LSI) infrared and electro-optical systems and combines it with calculus and domain transformations to achieve a successful imaging system analysis. Ultimately, the steps in this book lead to results in quantitative characterizations of performance metrics such as modulation transfer functions, minimum resolvable temperature difference; minimum resolvable contrast, and probability of object discrimination. |
