R&D Report 1957-13 : The construction and design of dichroic mirrors K. Hacking The somewhat stringent optical performance of beam-splitting dichroic mirrors imposed by three-colour television can be satisfactorily achieved with present-day apparatus and techniques for preparing multilayer interference films. A guide to the design and performance of such mirrors is afforded by considering the effects of the several physical parameters in idealized systems of layers...

R&D Report 1972-32 : A note on dichroic gratings for colour encoding K. Hacking The information-encoding action of a pair of dichroic gratings (sometimes known as striped filters) is analysed in general terms, using the effect on the spatial frequency spectrum of the image of a scene to reveal their intrinsic properties. Two colour-television camera systems based on a single pick-up tube are discussed, and an attempt is made to assess the physical tolerances required in the construction of suita...

R&D Report 1956-30 : Colour Television: The adaptation of the NTSC system to UK standards Part 1: The colorimetry of analysis and synthesis W.N. Sproson, J.G. Ingleton The mathematical transformations involved in specifying the ideal analysis filters for a colour scanner are described using the notation of classical matrix algebra. The colorimetric performance of an actual scanner is evaluated in terms of MacAdam's just noticeable differences...

R&D Report 1966-69 : Specification of colour sensitometric parameters in colour film telerecording E.W. Taylor, G.D. Judd A description is given of a combination of the spectral characteristics of the cathode-ray tubes, absorption-type filters and dichroic mirrors that is suitable for colour film telerecoding purposes; the importance of minimising flare in the optical system is discussed.

R&D Report 1957-07 : Colour television: The adaptation of the NTSC system to UK standards Part 6: Display systems. C.B.B. Wood Three different methods of colour television display are discussed; these employ projection, three-tube direct-viewing and shadow-mask presentations. A description is given of some of the difficulties encountered in the design and construction of specimen displays of each type.
