Abstract

A small, simple device is designed which makes transmission holograms of arbitrarily large objects coated with a retro-reflective paint. It allows direct readout of (delta) Z values from observed interferometric fringes under double-exposure, time-averaged, or real-time conditions. Three such orthogonal devices can be used for simultaneous detection of (delta) x, (delta) y, and (delta) z displacements.
