  • Abstract
    The photodisplacement microscopy for depth probing and control of a silicon plate cross-section homogenity is developed, as the one-arm optical bridge with interference Newton fringes is used. For determining the thickness of a silicon plate and for visualising its cross-section the frequency dependence of the thermal waves penetration depth is measured.
