| Abstract: | A new scheme for making a simple, compact and cost-effective two-beam optical interferometer using a commercially available diffraction grating and a single plate holographic optical element is described. The procedure for the generation of holographic optical element using a diffraction grating and the related techniques to realize the proposed interferometer along with typical experimental results has been presented. The proposed interferometer is simple, works well with a single collimated beam, and is quite suitable for performing optical test studies on phase (transparent) objects in real-time. |
