We propose and demonstrate a compressive sensing (CS) framework for correlation holography. This is accomplished by adopting the principle of compressive sensing and thresholding in the two-point intensity correlation. The measurement matrix and the sensing matrix that are required for applying the CS framework here are systematically extracted from the random illuminations of the laser speckle data. Reconstruction results using CS, CS with thresholding, and intensity correlation are compared. Our study reveals that liminal CS requires far fewer samples for the reconstruction of the hologram and has wide application in image reconstruction.

In interferenceless coded aperture correlation holography (I-COACH), it is still difficult to obtain high-quality edge-enhanced results due to the suppression of the modulation characteristics of the coded phase mask by cross-correlation operation. Here, we propose a deep learning-based edge-enhanced reconstruction method for I-COACH. Unlike the conventional method, which requires recording the point spread hologram of the system.

This is because digital holography (DH) can only measure displacement along the direction of the sensitivity vector. To realize 3D displacement measurement, three DH setups are needed.

Lysosomal storage diseases (LSDs) are genetic disorders caused by enzyme deficiencies that lead to lysosomal dysfunction and progressive cell damage. Accurate visualization and quantification of lysosomal morphology and subcellular localization are essential parameters for understanding the pathology and disease progression of different LSDs, as well as for developing effective therapies. Here, we successfully identified and characterized lysosomes using a holo-tomographic flow cytometry (HTFC) technique, which allows for label-free, high-content, and high-throughput 3D imaging of lysosomal compartments in single live cells.

Background: Real-time 3-dimensional transesophageal echocardiography (3DTEE) data acquired during interventional procedures are displayed on 2-dimensional screens, limiting intuitive depth perception and spatial comprehension. The study objectives were to evaluate the feasibility of intraprocedural use of a holography display during structural cardiology procedures employing 3DTEE, and to assess the accuracy of offline linear measurements in 3DTEE datasets.
Methods: A prospective single-center study was conducted using the HOLOSCOPE-i to guide catheter-based procedures using intraprocedural 3DTEE.

Background: Triple-negative breast cancer (TNBC) poses significant challenges due to its aggressive nature and lack of targeted therapies. Understanding the cellular behaviors of TNBC is crucial for developing effective treatments.
Aims: This study aims to compare the morphological characteristics of non-tumorigenic MCF10A and aggressive MDA-MB-231 TNBC cell lines using advanced analytical techniques.
