Optical Scanning

Front Cover
CRC Press, Jul 19, 1991 - Technology & Engineering - 896 pages
0 Reviews
The first three chapters cover gaussian beam characteristics, system lens design, and image quality, forming a framework that clarifies and serves the scanning process. Subsequent chapters cover the physical scanning methods holographic, polygonal, galvanometric, resonant, acoustooptic, electrooptic
