This interferometer uses a λ/8 waveplate made from Liquid Crystalline Polymer in order to generate two output signals in quadrature. The λ/8 waveplate can be manufactured either on a beamsplitter face or on the mirror surface, reducing the cost and complexity of the optomechnical assembly. Experiment results show that resolution of 2pm was attained for the wavelength range 628-635nm. The range of operation of such interferometer can be extended if wavelength-dependent Heydemann correction is used. <br /> <br /> Full Text: <a class="file" href="/PLP/index.php/letters/article/view/7-36/412" target="_parent">PDF</a> <br /> <br /> <strong>References</strong> <ol> <li> D.
