Scatter Imaging using Digital Fourier Microscopy, Journal of Physics D:
Applied Physics 38 3590-3598 (2004), 2007 An approach reported recently by Alexandrov et al. 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.

Advanced NanoBiomed Research, Volume 5, Issue 4, April 2025.Ultrasound transducers can be used to pattern microscale particles. Herein, it is shown that dynamic patterning, i.e., varying pattern location and direction using transmit beamforming, can be achieved using a (clinical)‐phased array transducer without the need for a reflector. Moreover, initial acoustic patterning results on living cells are presented,

Automatic cross filtering for off-axis digital holographic microscopy
Results in Physics, 2020 Off-axis digital holographic microscopy (DHM) is a significant quantitative phase imaging (QPI) modality in a single shot. However, the reconstructed quality of the image in the off-axis DHM is governed by the spatial filtering in the spectral domain of ...
