Laser extensometer

Abstract

Drift-compensated and intensity-averaged laser-based system uses optical and photoelectric effects for precise measurement of small thermally-induced size changes. Final output signal is directly proportional to size of sample shadow and independent of laser intensity, detector dark current, and lateral motion of sample.
