Time domain diffuse optical spectrometer (450-1700 nm)
About
Time domain diffuse optical spectrometer will characterize accurately the absorption and reduced scattering of highly scattering media over 450-1700 nm.
Description
Time Domain Diffuse Optical Spectroscopy is a non-invasive optical tool to assess highly scattering media. Few examples are in vivo tissue diagnosis like bone quality assessment, brain functional monitoring, brain computer interface, non-destructive assessment of food quality, wood characterization and quality control of pharmaceutical tablets.
Technical specifications:
Wavelength Range: 450 to 1700 nm
Sample: solid or liquid scattering media
Sample size: depends on scattering properties of sample, for biological samples around 5x5x5 cm (discuss with the team).
Sources type: supercontinuum source
Detection system: single photon detector in combination with time to digital converter, Hybrid PMT, InGaAs PMT, Silicone photomultiplier (SiPM).
