Micro Camera

A micro camera is a compact imaging device that records visual information where conventional cameras are too large, making it valuable for minimally invasive neuroscience research. Its lens focuses incoming light onto a miniature image sensor, which converts photons into digital signals; optical design, illumination, sensitivity, and frame rate determine the resulting spatial and temporal resolution. Integrated into microscopes, endoscopic systems, or head-mounted instruments, micro cameras can capture neural tissue, fluorescence signals, or animal behavior during experiments. Their small size supports less restrictive recordings and more naturalistic studies of brain circuits, while image quality, heat generation, and signal-to-noise ratio remain important design considerations.

2013

Micro-particle image velocimetry (μPIV) is used to visualize paired images of micro particles seeded in blood flows which are cross-correlated to give an accurate velocity profile. Shear rate, maximum velocity, velocity profile shape, and flow rate, each of which has clinical applications, can be derived from these measurements.
