Redewendungen und ihr Gebrauch,structure in solids.. In this technique localized heating of a sample by a modulated laser beam produces a periodic temperature gradient in the fluid near the sample surface. The thermally induced gradient in the index of refraction of the fluid causes a periodic deflection of a laserprobe beam pass

Chinesische Staatsunternehmen verstehenational Symposium on Acoustical Imaging. This technique was proposed as a means of overcoming the ‘go and return’ time redundancy inherent in conventional pulse-echo C-scanning without recourse to parallel processing, as used in the real-time C-scanning system of Green et al.(1974).
