Abstract
A speckle correlation technique is proposed for the measurement of small object tilt. Theoretical analysis is formulated for a general case of object tilt. Simulation and experimental studies are performed to verify the outcome of theoretical predictions and accuracy in measurement. Sensitivity of tilt measurement is studied and quantified from observations made from object position in various longitudinal planes.
