A novel distance sensing technique using digital speckle shearing interferometry is outlined in this paper. The primary incentive for the development of this technique is of one that can be: (i) incorporated into any TV imaging system; (ii) used as a focusing mechanism; (iii) suited to measure from diffuse targets; and (iv) relatively insensitive towards the environment. Results obtained reveal the feasibility of further research and development of this technique for practical applications.
