Low-level light treatment ameliorates immune thrombocytopenia
Immune thrombocytopenia (ITP) is an immune-mediated acquired bleeding disorder characterized by abnormally low platelet counts. We reported here the ability of low-level light treatment (LLLT) to alleviate ITP in mice. The treatment is based on noninvasive whole body illumination 30 min a day for a few consecutive days by near infrared light (830 nm) transmitted by an array of light-emitting di...
متن کاملLow-light-level nonlinear optics with slow light
Electromagnetically induced transparency in an optically thick, cold medium creates a unique system where pulse-propagation velocities may be orders of magnitude less than c and optical nonlinearities become exceedingly large. As a result, nonlinear processes may be efficient at low-light levels. Using an atomic system with three, independent channels, we demonstrate a quantum interference swit...
متن کاملMechanisms of Low Level Light Therapy
The use of low levels of visible or near infrared light for reducing pain, inflammation and edema, promoting healing of wounds, deeper tissues and nerves, and preventing tissue damage has been known for almost forty years since the invention of lasers. Originally thought to be a peculiar property of laser light (soft or cold lasers), the subject has now broadened to include photobiomodulation a...
متن کاملModel-Free Power-Spectral-Density Estimation for Low-Light-Level CMOS Imaging Sensors
We report on a method to estimate the noise power spectral density (PSD) of a CMOS image sensor (CIS), without any prior analytical assumptions. The method is based on the swept time operation of the correlated double sampling (CDS) output of a low-light-level CIS. We illustrate the method’s applicability through a direct frequency domain analysis of noise contributions to the sensor performanc...
