Spatially resolved measurements of ballistic and total transmission in microscale tissue samples from 450 nm to 1624 nm.

ABSTRACT: We built a simple and versatile setup to measure tissue ballistic and total transmission with customizable wavelength range, spatial resolution, and sample sizes. We performed ballistic transmission and total transmission measurements of overlying structures from biological samples ex vivo. We obtained spatially resolved transmission maps to reveal transmission heterogeneity from five microscale tissue samples: Danionella skin, mouse skull bone, mosquito cuticle, wasp cuticle, and rat dura over a wide spectral range from 450 nm to 1624 nm at a spatial resolution of ∼25 µm for ballistic transmission measurements and ∼50 µm for total transmission measurements. We expect our method can be straightforwardly applied to measuring the transmission of other samples. The
