Among the various optics-based tools used in diagnostics, diffuse optics (DO) is rapidly emerging as one of the most attractive technologies. The technique is based on analyzing how light is absorbed ...

A significant feature of this field is visualizing and detecting cells and tissue. This involves the injection of fluorescent markers, into a living system, to follow dynamics of a cell and drug ...

Researchers have developed an optical biopsy system that can distinguish between cancerous and healthy liver tissue. The technology makes use of diffuse reflectance spectroscopy and lifetime ...

A fluorescence microscopy variant developed by ETH Zurich and the University of Zurich could help overcome issues of light scattering in deep-brain microangiography. As published in Optica, the ...

Diffuse reflectance spectroscopy (DRS), in which the diffuse and scattered light returning from a sample can reveal details of its composition, has been widely studied as a means to measure hemoglobin ...
