    Abstract: In a method of measuring a temperature value associated with melting, softening or decomposition of sample substances, an array of samples is deposited onto a support tray. -fhe support tray is placed onto a heating device provided with temperature sensing means, the support tray is illuminated, and the array of samples is observed by a imaging device. WNle varying the temperature of the heating device, the image data from the imaging device is fed to an image recording device and temperature values associated with each feed of image data are also recorded. The image data is reviewed to detect changes in the image, such as image intensity, at each or selected sample locations, and thetemperature of the heating device at an image change associated with a change in state of a sample is logged. Image processing software may be used to detect changes in the image, for example in the intensity of the image, at each sample location. The method may be used as a means for rapidly obtaining a melting point value for comparison of the physical characteristics of the members of a library of samples, especially polymer samples.

    Abstract: A method for colour coding of image data comprises providing image data having associated spatial frequencies, choosing a colour set in which to code the image data, providing a psychological colour space constructed from. colour values in the colour set that are positioned in the colour space with reference to effects of the spatial frequencies on human colour perception of the colour values, and selecting points in a psychological colour space that represent a range of colours for a colour scale for colour coding of the data. Each point selected in the psychological colour space is mapped to a corresponding point in a physical colour space to enable a colour represented by each selected point to be determined, and the determined colours are then arranged into a colour scale. Defining a colour scale with reference to a contextually tailored psychological colour space allows the colour scale to be linear or nonlinear with respect to human colour perception; this can be achieved by using a regularly or irregularly distributed selection of points in a linear or nonlinear psychological colour space. Once data values are assigned to the colours in the colour scale, the data can be colour coded according to the scale, and presented to an observer for interpretation.

    Abstract: A triple beam resonator (10) is provided with three beams or tines (12, 14, 16) aligned in parallel alongside each other and joined at a decoupling zone (18) at each end, which is in turn connected to the surrounding material. The central beam (14) is twice the width of the two outer beams (12, 16). The resonating element has a length of 15.5 mm, a thickness of 0.25 mm and beam widths of 2 mm and 1 mm. The distance between the beams is 0.5 mm. Finite element analysis predicts the modal behaviour with stress distribution and eigenfrequencies of the resonator (10). Thick-film PZT elements (20, 22) were printed on separate regions at each end of the central beam (14), where maximum stresses exist as the resonator (10) operates in its favoured mode of vibration. The PZT element (20) at one end drives the vibrations, while the PZT element (22) at the other end detects them. Positioning the PZT driving and sensing elements (20, 22) on the regions of maximum stresses maximises the degree of mechanical coupling between the active piezoelectric layer and the resonator for generation of both driving forces and sensing signals. Very high quality factors of 3100 and higher have been experienced. Furthermore, the resonator can be manufactures by batch production techniques while maintaining high reliability and reproducibility.

    Abstract: We disclose single- or few-moded waveguiding cladding-pumped lasers, superfluorescent sources, and amplifiers, as well as lasers, including those for high-energy pulses, in which the interaction between the waveguided light and a gain medium is substantially reduced. This leads to decreased losses of guided desired light as well as to decreased losses through emission of undesired light, compared to devices of the prior art. Furthermore, also cross-talk and inter-symbol interference in semiconductor amplifiers can be reduced. We also disclose devices with a predetermined saturation power. As a preferred embodiment of the invention, we disclose a single (transverse) mode optical fibre laser or amplifier in which the active medium (providing gain or saturable absorption) is of the fibre's cross section where the intensity of the signal light is substantially reduced compared to its peak value. The fibre may be cladding-pumped.
