20 November 1989 Field Shift Moire, A New Technique For Absolute Range Measurement
Author Affiliations +
Abstract
A new and novel technique is discussed that provides non-contact high resolution absolute measurements with moire interferometry. Field shift moire provides both a course absolute measurement and a high resolution relative measurement similar to a vernier caliper. Combining these measurements yields absolute high-resolution range information.
