Abstract
Brief descriptions of student laboratory works on laser interferometry: "Object deformation analysis by means of holographic interferometry" and "Small displacement investigation by means of double-exposure speckle-photography" are given in the present paper. Deformation bends of metal plates with rough surfaces are investigated in the first work. Arrangements for recording and reconstruction of virtual and real holographic images are presented. Calculation formula and experimental results are given. Small displacement of plane objects with rough surfaces - inclinations and transverse displacements are investigated in the second work. Calculation formula, arrangements for recording double-exposure specklegrams of a displacement and scheme for observations of Young fringes are given.
