A potential method for tracking neurovascular disease progression over time in preclinical models is multiphoton fluorescence microscopy (MPM), which can image cerebral vasculature with capillary-level resolution. However, obtaining high-quality, thr

SignificanceTwo-photon microscopy is used routinely forin vivoimaging of neural and vascular structure and function in rodents with a high resolution. Image quality, however, often degrades in deeper portions of the cerebral cortex. Strategies to imp

The inverse correlation time (ICT) is a key quantity in laser speckle contrast imaging (LSCI) measurements. Traditionally, ICT is regarded as a metric of blood flow, such as speed or perfusion. However, we highlight that ICT not only contains importa

We demonstrate a simple, low-cost two-photon microscope design with both galvo-galvo and resonant-galvo scanning capabilities. We quantify and compare the signal-to-noise ratios and imaging speeds of the galvo-galvo and resonant-galvo scanning modes

Here we introduce a fiber amplifier and a diamond Raman laser that output high powers (6.5 W, 1.3 W) at valuable wavelengths (1060 nm, 1250 nm) for two-photon excitation of red-shifted fluorophores. These custom excitation sources are both simple to

We report the design of a graduating hexagonal ring porous-core Photonic Crystal Fibre. The design was analyzed for various parameters like the effective mode area, confinement loss, material loss, etc. using the COMSOL Multiphysics software and a to

We propose a design of a rectangular porous-core Photonic Crystal Fibre (PCF) with a hexagonal-shaped lattice of air holes in the cladding. The design was analysed using COMSOL for different frequencies and different values of the Air Fill Factor (AF
