Abstract
Cepstrum-based interferometric microscopy (CIM) has risen as a groundbreaking digital holographic microscopy (DHM) technique that overcomes the conventional need of a clean/known reference beam for holographic recording. In CIM, two arbitrary complex object fields interfere each other to provide quantitative phase imaging (QPI) of both at once. Previous CIM implementations were validated using global-shutter (GS) cameras. However, rolling-shutter (RS) cameras provide several advantages, such as reduced price, high frame rate, low electronical noise, and small pixel size in spite of some drawbacks (flickering effect) that are overcome in this Letter. Hereby, we report on the validation of the CIM technique using rolling-shutter cameras including a novel, to the best of our knowledge, flickering correction approach. The performance of the approach is experimentally validated using calibrated phase objects and biological samples.
期刊介绍：
The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community.
Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
