Abstract: A method and system are disclosed for enhancing the visibility of features of an image. The method comprises the steps of acquiring image data corresponding to at least one image feature using sensing means; processing the image data to identify changes in adjacent data points corresponding to a boundary of the at least one image feature; and, generating modified image data corresponding to the processed image data.

Abstract: A laser is provided, suitable for use in laser displays, having a laser cavity defined by at least first and second mirrors, a lasing material positioned in an optical path within the cavity with an associated pumping source and wherein one of the mirrors has a reflective surface that is moveable so as to alter the length of the cavity at a rate sufficiently high to ensure that effects due to a speckle pattern, as perceived by an observer or detector of light generated by the laser, are reduced while preserving the instantaneous coherence of the laser light. Sufficiently rapid movement of the mirror surface ensures that any speckle pattern changes at a faster rate than can be detected by the human eye or by a detector so that speckle is no longer visible, or is at least considerably reduced.

Abstract: An improved fibre-optic cable termination which substantially reduces light losses and also facilitates cable termination in the field as opposed to the factory.According to this method the fibres are compressed by pushing the bundle, preferably sheathed in a thin glass ferrule, into a heated tool having a tapered hole. A protective metal coupling may be incorporated by heating a metal sheath with a tapered bore and pushing the glass sheathed bundle into the metal sheath. The metal sheath may then constitute a pin of a pin and socket optical coupling.In all cases the temperature and pressure are adjusted so that the individual fibres are squeezed into approximately hexagonal form so as to eliminate the interstices to a substantial extent. The temperature and pressure are, however, limited to prevent any substantial fusion and coalescing of fibres and consequent loss of the optical barrier between them.
