Fibre Optic Reflection Photometry on Blood

Cardiovascular Research, 1968
A two photocell assembly has been used to measure the light reflection of blood conducted by fibre optics. Fibre optic reflection spectra of oxygenated and reduced blood samples show an isobestic region around 850 nm. Non-specific variations of the light reflection from a mirror do not affect the ratio of detecting and compensating photocell outputs ...
