• Sommario/riassunto: This newly revised and updated edition of a classic Artech House book offers a current and complete introduction to the analysis and design of Electro-Optical (EO) imaging systems. The Second Edition provides numerous updates and brand new coverage of today's most important areas, including the integrated spatial frequency approach and a focus on the weapons of terrorists as objects of interest. This comprehensive reference details the principles and components of the Linear Shift-Invariant (LSI) infrared and electro-optical systems and shows you how to combine this approach with calculus and d.
