The perception of light is inherently different inside a virtual reality (VR) or augmented reality
(AR) simulation when compared to the real world. Conventional head-worn displays (HWDs) …

Introduction: Laser hair removal needs an accurate understanding of tissue structure and
chromophores content in order to optimize the selection of laser irradiation parameters …

We present theoretical and experimental results of Lévy flights of light originating from a
random walk of photons in a hot atomic vapor. In contrast to systems with quenched …

Human tissue is one of the most complex optical media since it is turbid and
nonhomogeneous. We suggest a new optical method for sensing physiological tissue state …

Polarized and wide-field light microscopy has been studied for many years to develop
accurate and information-rich images within a focused framework on biophysics and …

Photodynamic therapy (PDT) is a method of treating cancer that combines light and light-
sensitive drugs to selectively destroy cancerous tumours without harming the healthy tissue …

Photoplethysmography (PPG) is a technique that uses light to noninvasively obtain a
volumetric measurement of an organ with each cardiac cycle. A PPG-based system emits …

The recent development of optogenetics, a revolutionary research tool in neuroscience,
portends an evolution of current clinical neuromodulation tools. A form of gene therapy …

Optical phantoms that simulate light propagation processes through soft biological tissue are
required to evaluate the performance and calibrate different medical imaging modalities …

A newly designed instrument, the static light-scattering (SLS) microscope, which combines
light microscopy with SLS, enables us to characterize local light-scattering patterns of thin …
