Beschreibung
Zusammenfassung:	FIELD: optical engineering. ^ SUBSTANCE: method can be used for optical images received from holograms. According to the method, two-exposition object hologram is made by sin out-of-axis scheme. Interfering wave fields are restored from hologram by strong coherent radiation received from tested object. Interference pattern is registered at the direction of initial reference beam. ^ EFFECT: simplified process of finding deformations of objects. ^ 6 dwg
