Continuous blood flow visualization with laser speckle contrast imaging during neurovascular surgery
Neurophotonics, 2022 . Significance: Laser speckle contrast imaging (LSCI) has emerged as a promising tool for intraoperative cerebral blood flow (CBF) monitoring because it produces real-time full-field blood flow maps noninvasively and label free.

Polychromatic speckle reduction in laser pico-projectors using stationary dual Hadamard diffusers [PDF]
Journal of the European Optical Society-Rapid Publications, 2014 Speckle from coherent light sources continues to be a limiting factor in the design and manufacturing of laser projectors. Utilizing diffractive diffusers has been an effective method for reducing monochromatic speckle contrast.

Multi-scale laser speckle contrast imaging of microcirculatory vasoreactivity.
Biomedical Optics Express, 2022 Laser speckle contrast imaging is a robust and versatile blood flow imaging tool in basic and clinical research for its relatively simple construction and ease of customization. One of its key features is the scalability of the imaged field of view. With

Laser speckle reduction based on angular diversity induced by Piezoelectric Benders [PDF]
Journal of the European Optical Society-Rapid Publications, 2013 Speckle reduction techniques have been investigated in display systems with coherent light sources. We propose a simple but efficient method to reduce speckle via two fast vibrating piezoelectric benders.
