Optical sectioning in wide-field microscopy is achieved by illumination of the object with a continuously moving single-spatial-frequency pattern and detecting the image with a smart pixel detector array. This detector performs an on-chip electronic signal processing that extracts the optically sectioned image. The optically sectioned image is directly observed in real time without any additional postprocessing.

Objective: Aim: To find out new objective criteria for laser histological differential diagnosis of thyroid pathology based on the use of a digital method of layer-by-layer polarization-interference mapping of polarization ellipticity maps of microscopic images of native histological sections of thyroid biopsy.
Patients And Methods: Materials and Methods: Four groups of patients were studied: control group 1 - healthy donors (51 patients); study group 2 - patients with nodular goiter (51 patients); study group 3 - patients with autoimmune thyroiditis (51 patients); study group 4 - patients with papillary cancer (51 patients). Methods used: polarization-interference, statistical.

This study aimed to identify brain activity modulations associated with different types of visual tracking using advanced functional magnetic resonance imaging techniques developed by the Human Connectome Project (HCP) consortium. Magnetic resonance imaging data were collected from 27 healthy volunteers using a 3-T scanner. During a single run, participants either fixated on a stationary visual target (fixation block) or tracked a smoothly moving or jumping target (smooth or saccadic tracking blocks), alternating across blocks.

Marine vessels play a vital role in the global economy; however, their negative impact on the marine atmospheric environment is a growing concern. Quantifying marine vessel emissions is an essential prerequisite for controlling these emissions and improving the marine atmospheric environment. Optical imaging remote sensing is a vital technique for quantifying marine vessel emissions.

Understanding how molecular aggregation influences nonlinear optical properties is essential for advancing organic fluorophores in imaging, sensing, and photonic applications. However, the relationship between the molecular aggregation and the magnitude of nonlinear two-photon absorption cross-section remains underexplored. Here, we systematically investigate the aggregation-dependent two-photon absorption properties of the fluorophore TPAPhCN by tuning the degree of aggregation.
