In optical character recognition systems, the identification of a character facilitated by means of known factors governing its appearance in a particular context; e.g., the first character in the...

A method in optical character recognition in which a mobile light beam scans the outlines of characters for subsequent reading of these outlines.

Any known value derived from standard analysis that serves as a reference to the accuracy of an instrument or process in determining one or more variables.

Calorimetry is a branch of science that involves the measurement of heat flow in physical or chemical processes. It encompasses various techniques and instruments used to quantify heat transfer,...

In analysis, the carbon layer that is evaporation-deposited on a specimen to protect and ready it for study by electron microscopy.

An instrument that detects high-energy charged particles by analysis of the Cerenkov radiation that they emit.

The field of microscopy as applied to chemical problems and analysis.

A type of spectroscopy used extensively in the analysis of biological samples. Because most biologically synthesized molecules, such as proteins, are optically active, circular dichroism spectroscopy...

The detection and analysis of the relative response of a material to light over the range of wavelengths.

In analysis, a reference spectrum, having predetermined wavelengths, that is used to determine the wavelengths of another spectrum through comparison of the two.

Computer vision enables computers to interpret and make decisions based on visual data, such as images and videos. It involves the development of algorithms, techniques, and systems that enable...

The use of computer analysis in the calculation of diffraction patterns for information on the design of optical systems. In this method, the electric field amplitude and phase in the aperture are...

Cresyl violet, also known as cresyl violet acetate or cresyl echt violet, is a synthetic organic compound belonging to the class of triarylmethane dyes. It is commonly used in histology and...

The spectrographic analysis of matter that is in a cooled state. Generally, a mechanical refrigerator is used to lower the temperature of the sample, allowing isolation and study of the sample and...

A device designed to measure crystal properties by analysis of crystal diffraction.

The analysis of the atomic structures within crystals by means of x-ray diffraction.

The analysis of light in the blue region of the visible spectrum.
