Abstract: Abstract This study presents a method for detecting small wavelength shifts using grating diffraction effect and high-angular-sensitivity total-internal-reflection (TIR) heterodyne interferometry. In the proposed interferometer, a half-wave plate and a quarter-wave plate that exhibit specific… read more here.
