A photometric coagulometer

Medical & Biological Engineering, 1976
The reduction of transmitted light at 650 nm caused by scattering from fibrin polymers as they develop in a clotting plasma sample has proven effective for following the course of the coagulation. An instrument designed on this principle and using entirely solid-state electronics has yielded clotting time reproducible to within ±15%, and has enabled ...

Analysis of photometric factors based on photometric linearization

Journal of the Optical Society of America A, 2007
We propose a method for analyzing photometric factors, such as diffuse reflection, specular reflection, attached shadow, and cast shadow. For analyzing real images, we utilize the photometric linearization method, which was originally proposed for image synthesis.

Photometric Displacement Transducer

IEEE Transactions on Biomedical Engineering, 1969
Measurements of variations in intensity of light reflected from a moving surface provide a method for quantitating displacement. A system to monitor displacements of a few microns is easily constructed. This technique has wide application in biological experiments, offering the advantage of probeless displacement monitoring.
