Abstract

A basic conception of an adaptive, remote optical sensor for small angle tilt displacement in 3D space is presented. Sensor is based on high space resolution 11,000 lines/mm adaptive photorefractive gratings has no moving parts is portable, robust and can provide measurement in plane and out-of-plane displacements simultaneously. Resolution of small angle tilt measurement of order of 10^-5 Rad has been achieved. Advantages and disadvantages of this sensor are discussed.
