Learn more about highly effective, economical Laser Speckle Perfusion Imager that allowing capturing of dynamic motion with high spatial resolution.

With the advantages of its non-contact, high time resolution, high spatial resolution, and full-field rapid imaging, it provides a real-time dynamic blood flow monitoring and recording method for research in life sciences. The transmissive laser speckle imager is an instrument where the laser source is opposed to the detector instead of alongside. Finally, Forrester et al. 42 reported on a new endoscopic apparatus that was used to image the rabbit joint capsule tissue in vivo .

Optotune Laser Speckle Reducers remove local interferences and significantly reduce speckle noise in laser systems by dynamically diffusing the laser beam. Offering a compact size, integrated drive electronics, and vibration-less speckle reduction, Optotune Laser Speckle Reducers are ideal for beam homogenization, 3D scanning, metrology, microscopy, and interferometry. WHAT IS THISMerry Christmas, lets talk about lasers! There are red lasers; there are green lasers - and they all speckle.

Using a webcam to perform LSCI. Post-stroke blood flow deficit imaged using an inexpensive LSCI system comprised of a webcam, plastic aspheric lenses, and a laser pointer. Speckle patterns can severely degrade the image quality of laser projection displays, or disturb position measurements with laser pointers. Speckle can often be avoided, e.g.

IEC 62906-5-4:2018(E) specifies the fundamental colour speckle distribution in CIE colour systems and the measuring methods of the colour speckle of laser 

If a photographic plate or another 2-D optical sensor is located within the scattered light field without a lens, a speckle pattern is obtained whose characteristics depend on the geometry of the system and the wavelength of the laser. Laser speckle contrast analysis (LASCA), also known as laser speckle contrast imaging (LSCI), is a method that instantly visualizes microcirculatory tissue blood perfusion. It is an imaging technique that combines high resolution and high speed. LSCI is a non-invasive technique to measure blood perfusion. The method that visualizes tissue blood perfusion in real time.

Laser Doppler perfusion imaging (LDI) is currently used in a variety of clinical applications, however, LDI instruments produce images of low resolution and have long scan times. A new optical perfusion imager using a laser speckle measurement technique and its use for in vivo blood flow measurements are described. Measurements of human skin and surgically exposed rabbit tissue made using this
