How to Build a Laser Speckle Contrast Imaging LSCI System

Although Laser Doppler technique is a traditional approach for monitoring blood flow, it can only measure from a single point with very narrow (less than 0.1 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. Laser speckle contrast is a useful tool with applications in clinical practice and additional medical applications currently being researched. It is a technique that is versatile, simple, non-invasive, and inexpensive.

Here it is shown that deep learning is an ideal approach to analyze wavelength variations using a speckle wavemeter due to its ability to identify trends and overcome low signal to noise ratio in complex datasets. Laser speckle—the dazzling pattern of light and dark spots you see here—arises from a phenomenon known as wave interference.

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 Fast speckle suppression is crucial for time-resolved full-field imaging with laser illumination. Here, we introduce a method to accelerate the spatial decoherence of laser emission, achieving speckle suppression in the nanosecond integration time scale.
