OPTICAL DISTANCE SENSING USING DIGITAL SPECKLE SHEARING INTERFEROMETRY

A novel distance sensing technique using digital speckle shearing inte rferometry is outlined in this paper. The primary incentive for the de velopment of this technique is of one that can be: (i) incorporated in to any TV imaging system; (ii) used as a focusing mechanism; (iii) sui ted to measure from diffuse targets; and (iv) relatively insensitive t owards the environment. Results obtained reveal the feasibility of fur ther research and development of this technique for practical applicat ions. Copyright (C) 1996 Elsevier Science Ltd.
