Filed: 1947-12-24
Abstract: 638,238. Kinematograph cameras; reflectors. VINTEN, C. Dec. 24, 1947, No. 34136. [Class 97 (i)] [Also in Group XXII] A rotatable reflector element has an opticallyfinished reflecting surface on one face accurately perpendicular to the rotational axis, and a substantial portion of its opposite face accurately finished in relation to the reflecting surface to form a bearing surface for the element during its rotation. The form shown may be used as a reflecting shutter in a kinematograph camera such as described in Specification 597,269. To make this form a disc of metal is turned and portions milled away between the sectors 2, 3. The hole 5 for the driving shaft, the holes 6 for screws securing the reflector thereto, and the slots 7 are then drilled and metal removed from the centre of the front face to reduce weight. The front face, and the centre of the rear face, are then ground approximately flat and parallel, the portion of the rear face beyond the dotted line being conical to reduce the thickness of the disc progressively towards the periphery. The front faces of the flanges 2, 3 are then plated and ground and the disc approximately balanced, statically and dynamically, metal being removed as necessary, for example from the slots 7. The front faces of the flanges are then polished and the central bearing area on the back of the disc accurately ground with reference thereto. The reflector is then balanced accurately and the reflecting surfaces aluminized. The bearing surface may be conical or spherical instead of plane. To ensure accuracy the metal block is annealed after rough machining and long time periods allowed between subsequent operations, the block being kept at a substantially uniform temperature.

Abstract: 1409475 Light guides THOMSON-CSF 23 July 1973 [25 July 1972] 35082/73 Heading G2J [Also in Divisions H3-H5] A frequency multiplier of optical radiation utilizes the harmonic generation resulting from non linear interaction which obtains when fundamental radiation is totally internally reflected at an interface separating two media of different refractive indices. As shown in Fig. 1, optical radiation is propagated along a zig-zag path 33 through a dielectric waveguide layer 1, such as glass, total internal reflection occuring at an upper air-layer interface, and at a lower interface between the layer and a metal, semi-conductor or dielectric film 2 carried by a substrate 3, the thickness of the waveguide layer being such that the phase velocities of the fundamental optical radiation and the generated harmonic are matched. In a modification, Fig.3, the dielectric layer 51 is overlaid by a further layer 52 of different refractive index, the radiation path 43 being as shown. Radiation is coupled into and out of the waveguide laye oy prisms 10 and 11 which may be spaced from the layer by a distance approximating to the radiation wavelength, or may be in direct or pressurized contact. An alternative input coupling, Fig.5, comprises a phase grating 40 which may be a holographic phase grating recorded in a photo-sensitive material previously deposited on the layer 1. Injection of the incident radiation into a thickness-tapered end of the layer is also suggested. Amplitude modulation of the fundamental and harmonic radiation may be obtained by the electro-optic effect in layer 1 produced by electric field electrodes 61, 62, Fig.6, implanted in an electrically non-conducting film 2 formed e.g. of silicon. In a modified modulator Fig.8 (not shown), the electrodes are respectively positioned adjacent opposite major surfaces of the layer.
