An optical fiber within that device emits laser light onto the vessel walls – that light is partially absorbed and partially scattered back by any plaque deposits it encounters. The scattered light ...

It sure sounds like “laser speckle imaging” is the sort of thing you’d need grant money to experiment with, but as [anfractuosity] recently demonstrated, you can get some very impressive results with ...

Despite the long-standing reputation of each, as well as distinct underlying physics, laser speckle contrast imaging (LSCI) and imaging photoplethysmography (IPPG) reach concordance on functional ...

The challenge of recovering image data from objects hidden from direct observation or concealed by corners, termed non-line-of-sight imaging (NLoS), can be tackled in several ways, often involving ...

It sure sounds like “laser speckle imaging” is the sort of thing you’d need grant money to experiment with, but as [anfractuosity] recently demonstrated, you can get some very impressive results with ...

Design, development and validation of a speckle-based, visible spectrum, image sensor modulation transfer function (MTF) test system. Investigated the technique of using visible (532nm) laser speckle ...

Measuring blood flow in the brain is critical for responding to a range of neurological problems, including stroke, traumatic brain injury (TBI) and vascular dementia. But existing techniques, ...
