A common issue amongst these DHM systems is that the two replicas of the sample\u2019s information overlay due to self-interference, making them only suitable for imaging sparse samples. This overlay has restricted the use of common-path DHM systems in material science. The overlay can be overcome by limiting the sample\u2019s field of view to occupy only half of the imaging field of view or by using an optical spatial filter. In this work, we have implemented optical spatial filtering in a common-path DHM system using a Fresnel biprism. We have analyzed the optimal pinhole size by evaluating the frequency content of the reconstructed phase images of a star target. We have also measured the accuracy of the system and the sensitivity to noise for different pinhole sizes. Finally, we have proposed the first dual-mode common-path DHM system using a Fresnel biprism. The performance of the dual-model DHM system has been evaluated experimentally using transmissive and reflective microscopic samples.<\/jats:p>","DOI":"10.3390\/s22103793","type":"journal-article","created":{"date-parts":[[2022,5,17]],"date-time":"2022-05-17T04:04:19Z","timestamp":1652760259000},"page":"3793","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Single-Shot 3D Topography of Transmissive and Reflective Samples with a Dual-Mode Telecentric-Based Digital Holographic Microscope"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0448-376X","authenticated-orcid":false,"given":"Ana","family":"Doblas","sequence":"first","affiliation":[{"name":"Department of Electrical and Computer Engineering, The University of Memphis, Memphis, TN 38152, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Charity","family":"Hayes-Rounds","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, The University of Memphis, Memphis, TN 38152, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rohan","family":"Isaac","sequence":"additional","affiliation":[{"name":"FedEx Institute of Technology, The University of Memphis, Memphis, TN 38152, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0208-9761","authenticated-orcid":false,"given":"Felio","family":"Perez","sequence":"additional","affiliation":[{"name":"Material Science Laboratory, Integrated Microscopy Center, The University of Memphis, Memphis, TN 38152, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"054032","DOI":"10.1117\/1.2357174","article-title":"Digital holographic microscopy for the three-dimensional dynamic analysis of in vitro cancer cell migration","volume":"11","author":"Dubois","year":"2006","journal-title":"J.
