Poor blood flow circulation can occur in the subcortical regions of the brain in many brain diseases. However, the limitations of light penetration imaging techniques hinder the detection of blood flow in deep brain tissues in vivo. Hence, in this Letter, we present a gradient index lens-based laser speckle contrast imaging system for time-lapse blood flow detection in subcortical regions of

The first biomedical application was reported by Fercher and Biers. 2 The technique proposed by Fercher and Briers was non-real-time and had practical limitations due to the use of nondigital systems, which impeded the clinical use. The moorFLPI-2 blood flow imager uses the laser speckle contrast technique to deliver real-time, high-resolution blood flow images, providing outstanding performance in a wide range of pre-clinical and clinical research applications. Optical zoom means you can assess small areas right up to a full size adult hand with a single imager. In-line laser speckle reducer (fiber optical beam homogenizer, or De-Speckler) significantly homogenizes speckle pattern and reduces the unwanted laser speckle noise (modal noise) in multimode optical fiber, producing a stable output beam that has fewer speckle hot spot and more uniform energy intensity profile.

This project is based on the observation by Lisa Richards et al at the University of Texas who noted that a medical imaging technique called laser speckle contrast imaging could be done with inexpensive and commonplace hardware: specifically a laser pointer and a webcam.

Optotoune's laser speckle reducers are nothing else than moving diffusers. But the way they are actuated is absolutely unique. Within a height of less than 1mm, electroactive polymers are used to generate an oscillating motion (e.g. 400µm travel at 300Hz).

To conclude we present results that show that the speckle contrast can be reduced to C = 0.11 ± 0.02 at a temperature of 30ºC and demonstrate the improvement of the quality of an image generated using a modified commercial projector fitted with a monochromatic laser source. Laser speckle flowmetry The technique for LSF has been described in detail else-where (Dunn et al., 2001). Briefly, a CCD camera (Cohu, San Diego, CA, U.S.A.) was positioned above the head, and a laser diode (780 nm) was used to illuminate the skull surface in a diffuse manner. The penetration depth of the laser is approxi- The speckle pattern produced when a laser is scattered by a disordered medium has recently been shown to give a surprisingly accurate or broadband measurement of wavelength.
