Abstract. Development of holographic methods and instruments for control over stressedly-deformed state of diffusely reflecting object adapted to employment in automated measuring systems is discussed. A concept design is proposed of a system for measuring local slopes of the object surface with optical processing of double-exposed holographic interferograms.
Keywords: holographic interferometry, shearing interferometer, diffusely reflecting object.
