Paper Abstract

We propose a novel method for high accurate three-dimensional angle measurement based on propagation vector analysis of digital holography. 3D rotations in space can be achieved by use of a CCD camera and a multi-facet object, which reflects an incident wave into different directions. The propagation vectors of the reflected waves from the object can be extracted by analyzing the object spectrum of the recorded hologram. Any small rotation of the object will induce the change of the propagation vectors in space, which can then be used for 3D angle measurement. Experimental results are presented to verify the idea.
