摘要： An optical mode filter, that is, an optical component in which the basic mode can propagate undamped as much as possible but which in higher modes are strongly damped. The optical mode filter, is an integrated optical wave guide formed by, a higher-refracting or an absorbent material disposed near a flat wave guide core. Two buffer layers are located opposite the wave guide core, and one is formed with a thinned region to function as a filter for higher modes being transmitted through the wave guide core.

摘要： The invention relates to an optical telecommunications network comprising several nodes (N1 to N4) connected to one another by optical transmission paths that form several working rings (R1 to R4), each of which passes via each node. Information is transmitted in the network at several different wavelengths. To ensure that the network can be implemented as cost-effectively as possible, it comprises a group of nodes (N1 to N4) including N nodes, a group of working rings (R1 to R4) including N rings, and a group of wavelengths (λ1 to λ4) including N wavelengths in such a way that each node in the group of nodes is configured to transmit signals at one wavelength in the group of wavelengths to all rings in the group of rings except to the ring from which it receives signals, and to receive signals at all wavelengths in the group of wavelengths except for its own transmitting wavelength from both directions in only one of the rings in the group of rings. Each node has an individual wavelength specific to the node, the said wavelength being one of wavelengths in the said group of wavelengths, and a reception ring specific to the node, from which the other nodes in the group of nodes do not receive.

摘要： The invention relates to the implementation of multiplexing and demultiplexing of optical signals. The multiplexing and demultiplexing are carried out by using the same waveguide phased array component (WGA). On the first side, the component comprises at least an input port and an output port (IG, OG), and on its second side a first group of ports that constitute the demultiplexer function output ports, and a second group of ports that constitute the multiplexer function input ports. An optical input signal is applied to the input port, such an input signal comprising a number of signals each at its own wavelength, the input signal is demultiplexed in the component and the demultiplexed signals are coupled to ports of the first group. The signals to be multiplexed are applied to ports of the second group and the multiplexed signal is coupled to the output port (OG). To reduce crosstalk, the signals at different wavelengths and the signals to be multiplexed are demultiplexed and applied, respectively, to alternate second side (B) ports so that the second side ports alternately have a port belonging to the first group and a port belonging to the second group.

摘要： An apparatus for panoramic X-ray photography of the area of the dentition and the jaws, comprising a frame part, a bearing part linearly movable in relation to the frame part, and a support arm attached rotatably to the bearing part, the arm having at one end an X-ray film and at the opposite end an X-ray source. The movements of the bearing part, the support arm and the film are synchronized in such a way that an image of an area of desired shape, e.g. the patient's dental arch, is obtained on the film. The invention provides a possibility, without shifting the patient, of altering the enlargement and, additionally of tilting the X-ray beam a desired angle in relation to the horizontal, whereby e.g. teeth oblique in relation to the vertical can be photographed more sharply. The support arm is attached to the bearing part through structural parts provided with guides extending in the longitudinal direction of the support arm, and with transfer means, so that the support arm, with the source of radiation and the X-ray film, can be transferred in a direction parallel to the X-ray beam. Furthermore, the said structural parts also have curved rails cooperating in order to effect tilting of the support arm. The movements are effected by stepping motors.

摘要： An apparatus for panoramic X-ray photography of the area of the dentition and the jaws, comprising a frame part, a bearing part linearly movable in relation to the frame part, and a support arm attached rotatably to the bearing part, and having at one end an X-ray film and at the opposite end an X-ray source. The movements of the bearing part, the support arm and the film are synchronized in such a way that an image of an area of desired shape, e.g. the patient's dental arch, is obtained on the film. The invention provides the effect that the X-ray beam can be tilted to a desired angle in relation to the horizontal, whereby it is possible with greater sharpness to photograph, for example, teeth slanted in relation to the vertical. For this purpose, the support arm is tiltable about an axis perpendicular to its rotational axis so that, when this axis is vertical, the straight line connecting the source of radiation and the film is obligue to the horizontal. The structural parts between the bearing part and the support arm are provided with co-operating curved guide means, the mutual movement of which alters the tilt position of the support arm. The control movements are performed by stepping motors.
