High-throughput spectroscopic microtomography in the short-wave infrared range
Abstract:
Spectroscopic microtomography nondestructively measures the attenuation coefficient of a complex microspecimen over a wide wavelength range. The imaging throughputs of existing approaches are kept very low by requiring scanning mechanisms for both spectroscopy and tomography. In this work, we demonstrate high-throughput spectroscopic microtomography in the short-wave infrared (SWIR) range using snapshot optical tomography and Fourier transform spectroscopy. Using the developed system, we measure the attenuation coefficient spectra of the hair medulla and cortex in the 1100-1600 nm wavelength range.
