Title: Optical wavelength-multiplexing and/or demultiplexing device
Inventor: DANMANN HANS
IPC: G02B6/293
Filed: 1983-04-11
Abstract: The invention relates to an optical wavelength multiplexing and/or demultiplexing device and comprises a digital phase grating 1 having at least four steps d, which grating diffracts light of at least three different wavelengths in different central diffraction orders F-1, F0, F+1. This grating is arranged in the radiation path of a first optical fibre (F) and effects branching of the light incident thereon to a number of receiving fibres positioned at points F-1, F0, F+1. Since the grating period g is large in comparison with the light wavelength, manufacture of a phase grating required for such a device is simplified, and the invention also allows light-emitting diodes, in addition to lasers, to be used as light sources. <IMAGE>

IPC: A61B8/00
Filed: 1985-03-15
Abstract: Apparatus for interpolating data obtained (20) along radial lines, so that it can be displayed (26, 28, 30) at display points ( + ) arranged in orthogonal rows and columns, by recursively adding stored values to derive signals indicative of the radial position of each display point along the radial data lines and its angular position between the radial data lines. Interpolation is done (24) along each radial line to derive first and second intermediate interpolated values, and these values are interpolated so as to derive the final data value for the display point at its angular position. Alternatively, the intermediate interpolated values can be attained by angular interpolation and the final data value by radial interpolation. <IMAGE>
