Frequency domain diffuse optical multiplexing system for rapid hemodynamics

Not Accessible

Your library or personal account may give you access

Abstract

A novel instrument, containing 5 wavelengths, 15 sources and 8 detectors is developed for spatially resolved near infrared spectroscopy in the frequency domain. By combining Frequency-Division Multiplexing and Time-Division Multiplexing techniques, one frame of measurement can be acquired in less than 1 second.
