Holographic digital Fourier microscopy for selective imaging of biological tissue

Fourier-domain digital holographic optical coherence imaging of living tissue.

Digital holographic optical coherence imaging is a full-frame coherence-gated imaging approach that uses a CCD camera to record and reconstruct digital holograms from living tissue. Recording digital holograms at the optical Fourier plane has advantages for diffuse targets compared with Fresnel off-axis digital holography. A digital hologram captured at the Fourier plane requires only a 2D fast...

Biological imaging by Digital Holographic Adaptive Optics

The basic principles of DHAO have been presented and demonstrated in a recent paper [Opt. Lett. 36, 27102712(2011)]. In this paper, the application of DHAO in biological imaging is investigated. OCIS codes: 090.1995; 110.1080

Optical Scatter Imaging using Digital Fourier Microscopy

An approach reported recently by Alexandrov et al. 1 on optical scatter imaging, termed digital Fourier microscopy (DFM), represents an adaptation of digital Fourier holography to selective imaging of biological matter. Holographic mode of recording of the sample optical scatter enables reconstruction of the sample image. Form-factor of the sample constituents provides a basis for discriminatio...

Quantitative Analysis of Biological Cells Using Digital Holographic Microscopy

Accurate single-shot quantitative phase imaging of biological specimens with telecentric digital holographic microscopy.

The advantages of using a telecentric imaging system in digital holographic microscopy (DHM) to study biological specimens are highlighted. To this end, the performances of nontelecentric DHM and telecentric DHM are evaluated from the quantitative phase imaging (QPI) point of view. The evaluated stability of the microscope allows single-shot QPI in DHM by using telecentric imaging systems. Quan...
