Classification of Photometric Factors Based on Photometric Linearization
2006We propose a new method for classification of 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. First, we show that each pixel can be photometrically classified by the simple

Photometric titrations—IIDesign and construction of a photometric titrator
Talanta, 1961Abstract The construction of a simple photometric titrator is described. The light receptor is a photo-diode whose design makes it easily possible to exclude external light. Consequently, titrations can be performed with the titration vessel in the open.

This paper describes how information about the configuration of the cornea can be derived from the raw data obtained with telecentric photokeratometers, and how such data can be expressed and used. It also deals with the interrelations of the different ways of expressing the data.

Abstract The recent growth of astrophysics emphasizes the differences that exist between the photometric nomenclature of physics and that of astronomy. Astronomers employ such concepts as “brightness,” “luminosity,” and “magnitude”; but these same words are used with entirely different meanings by astronomers and by physicists.

Photometric Quantitation of Haemagglutination
Scandinavian Journal of Haematology, 1967A modified technique for photometric quantitation of haemagglutination was employed in experiments with anti‐A test sera and Arcell suspensions. The agglutinates and the free cells were separated by simple sedimentation. As an absolute separation was impossible in this way, no exact estimation of percentage agglutination could be made.
