The characteristics of 2-D holographic scanners utilizing a concave auxiliary reflector are analyzed. The total resolution capability of the scanner is discussed in detail for the scanner operated at both finite and infinite conjugations, and the factors limiting resolution are indicated. The resolution considerations lead to a near-optimal design procedure which is used in design examples for typical applications in the visible, millimeter, and ultrasonic wavelength regions.
