Abstract: 1,257,858. Relief model. D. R. SKINNER. 2 Dec., 1970 [12 Sept., 1969], No. 45049/69. Heading G5G. A method of making a model of an area comprises forming a reversed photo-engraving of a contour map of the area on a flat sheet 1 of metal or plastics, preparing a rigid base 8 having a surface contoured in accordance with the map, and mounting the sheet in contact with the base with the engraved surface outermost. The sheet may be. of nylon, or of a metal such as zinc or copper, in which case incisions are made in the sheet at right angles to the contour lines and at. intervals therealong. This enables the sheet to be bent in conformity with the contours. Resulting apertures are filled with an epoxy resin or soft solder.

Collinated light from a slit 2 is received by three photo-voltaic cells after passage through the two gratings, which preferably have different pitches. The photo-cells are located so that the signals from differential amplifiers 10, 11 are in phase quadrature. These two signals are then supplied to a bi-directional counter which displays the number of quarter cycles of the signals. For measuring angular movement, the gratings may be of the radial or drum variety. In a further embodiment, the light pattern is derived from a laser interferometer having an optical wedge (25) in the fixed-length reference path Fig. 6, (not shown). A corner cube mirror (27) is attached to the object whose movement is to be monitored, this mirror defining the measuring path. The interference pattern is observed by three detectors whose outputs are arranged as shown in Fig. 1.
