When a biological tissue is illuminated with coherent light, an interference pattern will be
formed at the detector, the so-called speckle pattern. Laser speckle contrast imaging (LSCI) …

Dynamic light scattering (DLS) is a well known experimental approach uniquely suited for
the characterization of small particles undergoing Brownian motion in randomly …

Background Flowmotion is the rhythmical variations in measured skin blood flow that arise
due to global and local regulation of the vessels and can be studied using frequency …

Enabling handheld perfusion imaging would drastically improve the feasibility of perfusion
imaging in clinical practice. Therefore, we examine the performance of handheld laser …

In this work we introduce a modified form of laser speckle imaging (LSI) referred to as affixed
transmission speckle analysis (ATSA) that uses a single coherent light source to probe two …

Objective: To enable a real-time surgical guidance system that simultaneously monitors
blood vessel perfusion, oxygen saturation, thrombosis, and tissue recovery by combining …

Laser speckle imaging (LSI) is a wide-field, noninvasive optical technique that allows
researchers and clinicians to quantify blood flow in a variety of applications. However …

Laser speckle contrast imaging (LSCI) is used in clinical research to dynamically image
blood flow. One drawback is its susceptibility to movement artifacts. We demonstrate a new …

Significance: Intraoperative parameters of renal cortical microperfusion (RCM) have been
associated with postoperative ischemia/reperfusion injury. Laser speckle contrast imaging …

Noncontact photoplethysmography (PPG) is limited by a poor signal-to-noise ratio (SNR). A
solution to this limitation is the use of alternate sources of optical contrast to generate a …
