| Abstract | A pure-optical quadratic phase compensation method is proposed for the image-plane digital holographic microscope. Theoretical analysis testifies that the quadratic phase can be removed completely only when the reference point source is rightly located at the back focal plane of the microscope objective. The image-plane digital holographic microscopy is built, in which the well located sphere reference beam directly emitting from the tip of the fiber is utilized as the reference beam. Experimental results reveal how the quadratic phase curvature changes with the scanning of the reference point source, and make the adjustment of the reference beam visualized and operable. The effectiveness of the proposed method is demonstrated by the quantitative three-dimensional measurement of a microlens array and the morphological monitoring of living mouse fibroblast cells. The quadratic phase aberration can be compensated inherently without any computation, which greatly eases the computation load in the reconstruction of the digital hologram and helps to improve the real time of imaging system. Besides, the adjustment and alignment of the quadratic phase free image-plane digital holographic microscope is practicable and convenient. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
