Basic ElectroOptics for Electrical Engineers (SPIE Tutorial Texts in Optical Engineering Vol. TT31)

Introduces imaging, radiometry, sources, detectors, and lasers, with special emphasis on flux-transfer issues. The first-order approach enables students to make back-of-the-envelope calculations needed for initial set-up of optical apparatus. Intended for students and newcomers to electro-optics.
