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 ...

Saao standards for optical photometry

Astrophysics and Space Science, 1995
A review is given of the development of systems of photometric standard stars at the South African Astronomical Observatory. A brief historical perspective indicates how the Harvard E-regions were chosen as standard sequences and developed into a very precise Southern hemisphere system for UBV(RI) c photometry ...

Tapered Optical Fibers for Fluorescence Lifetime Photometry

Conference on Lasers and Electro-Optics, 2021
We describe a system exploiting a multi-anode array placed in the far-field plane of a tapered optical fiber to perform fluorescence lifetime photometry with depth-resolution in brain tissue.
