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, 2007We 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.

GAIA Photometric System: Simulation of Photometric Observations
Astrophysics and Space Science, 2002We present a software package developed for modelling of the GAIA photometric observations. The modelling procedure is very flexible and fully controlled via the parameter file. Therefore, configuration of the GAIA telescopes and photometric systems, as well as the object samples under investigation, can be adjusted easily.

Photometric devices, especially those intended for the measurement of color, must be highly sensitive to small differences if they are to give useful information.

Abstract Photometric methods are the most frequently used of all kinds of enzyme assay. They are convenient and capable of rapidly providing accurate and reproducible results on large numbers of samples. Useful changes in the optical properties of the system under analysis frequently arise directly from the chemical transformations ...
