I. The past. the present ... and the future It is possible to take the view that ever since it began, the "ancient" branch of physics known as Optics has been concerned with processƯ ing images. But since the Nineteen-Thirties increasingly close ties have been forming between Optics, which until then had been largely based on instruments, and the sciences of communication and inforƯ mation arising out of mathematics and electronics. Such developments follow naturally, since communication systems and image-forming systems are all designed to receive or transmit information. FurtherƯ more the same mathematical forms are used for describing the behaƯ viour of electrical and optical systems. It is a question of systems theory, particularly linear systems, and of Fourier's analysis methods, which together constitute an important part of Signal Theory. In the case of communication systems carrying signals of an electrical nature, information is time-related or temporal. Transmitted signals are one-dimensional and functions of a single variable, time t. In the case of optical systems information is spatial in nature. Signals are distributions of light intensity in space. In general they are treated as two-dimensional signals, being functions of two spatia! variables written as x and y. In the early Fifties the way forward became clearer still when some scientists at the Institut d'Optique in Paris began using optical filtering techniques in coherent light in order to enhance the quality of photographs

The Analysis of Smoke Dyes. II. The Determination of 1-Amino-4-Hydroxyanthraquinone in 1,4-Diaminoanthraquinone( Book )

1 edition published in 1974 in English and held by 1 WorldCat member library worldwide

Leuco 1-amino-4-hydroxyanthraquinone has been identified as an impurity in 1,4-diamino-2,3-dihydroanthraquinone. Identification of this impurity was made by visible and infrared spectroscopy and thin-layer chromatography. The amount of the impurity 1-amino-4-hydroxyanthraquinone can be quantitatively determined in the presence of 1,4-diaminoanthraquinone by converting the 1-amino-4-hydroxyanthraquinone to the anion by reaction with 0.03M KOH in ethanol. Anion formation is accompanied by a bathochromic shift in the visible region to 603 nm. (Modified author abstract)
