Title: Photothermal interferometry for nondestructive subsurface defect detection
Issue Date: 1986 Zeitschriftenartikel Optics communications 58 (1986), S. 295-299. URL
Abstract: A symmetrical interferometer as thermal expansion detector was developed for photothermal nondestructive material analysis. Phase and amplitude exchange phenomena have been observed, when introducing an electronic reference phase shifter mixed to the interferometer signal. Experimental and theoretical results obtained with this system are presented.
