Abstract: Methods and systems are provided for distinguishing between more than one fluorescent species present in a sample in fluorescence microscopy. The method involves illuminating the sample with at least one light source. More than two images of the illuminated sample are recorded over a period of time, each image comprising a plurality of pixels, wherein each pixel corresponds to a location in the sample and records a degree of fluorescence at the location in the sample at a particular point in time. A photostability characteristic of the degree of fluorescence at each pixel over the period of time over which the more than two images were recorded is determined and used to distinguish between the more than one fluorescent species present in the sample.

Abstract: The invention relates to multicore fiber imaging, such as used in endoscopy. Methods are described for processing images captured with such systems to achieve an improved depth of field image or extract 3D information concerning the images, without requiring the addition of additional optical components. One method for generating an image from light received by an imager via a multiplicity of waveguides includes receiving a digital image containing a plurality of pixels, the digital image including a plurality of regions within it wherein each of said regions corresponds to a waveguide core. Each region includes a plurality of pixels, and a first subset of pixels within each region is defined which at least partly correlates with light having been received at a corresponding core in a first spatial arrangement, the subset including less than all of the pixels within a region. A first image is generated from the first subset of pixels from said regions, combined to form an image over the whole waveguide array. The first spatial arrangement may correspond to a measure of angular dimension of the incident light for that region. In addition to increased depth of field, the modified images provided by the invention allow 3D visualisation of objects, eg. using stereographs or depth mapping techniques.

Abstract: A capsule adapted to be introduced into the digestive system and gastrointestinal (Gl) tract of a mammal which consists of a capsule shaped container consisting of a wall material capable of being bio compatible with the digestive system and being adapted to protect the electronic and sensor devices contained in the capsule. The capsule contains gas composition sensors operable at several temperature points for a short duration, a temperature sensor, a micro controller, a power source and a wireless transmission device. The capsule wall incorporates gas permeable membranes adjacent said gas sensors. The microprocessor is programmed to receive data signals from the sensors and convert the signals into gas composition and concentration data and temperature data suitable for transmission to an external computing device.

Abstract: A photonic processing module (100) comprises a high index-contrast waveguide device comprising a substrate (102), a first layer (104) disposed on the substrate having a first refractive index, and a relatively thin second layer (106) disposed on the first layer. The second layer has a second refractive index providing a high index-contrast with the first layer, and the device includes at least one thin-ridge waveguide element (108) formed in the second layer which supports a guided mode in a longitudinal direction. An optical input port (110) is configured to direct an input beam into a slab mode of the second layer, the beam being directed to propagate at a predetermined angle θ to the longitudinal direction of the thin-ridge waveguide element. The angle θ is associated with a resonant coupling between the slab mode of the second layer and the guided mode of the thin-ridge waveguide element. An output beam is thus generated when the input beam includes one or more optical components corresponding with the resonant coupling. An optical output port (112) is configured to receive the output beam.

Abstract: A sensor grid is provided which is able to provide signals of the magnitude and location on the grid of applied pressure. In the prime application of gait analysis, the sensor in the sole of a shoe provides over time a signal indicative of the magnitude and movement of the centre of pressure. This may be presented as a visual signal showing the location of the centre of pressure on the outline of the sole with pressure values coded in colour. Alternatively the location may be represented as pitch of an audio signal and the magnitude by sound volume. Such a signal can be used to provide feedback to a patient to correct their gait by modifying their gait to produce a desirable signal. The analysis software uses an algorithm to identify the location, speed and distribution of the centre of pressure (COP) and additionally to assess the fractal dimension of the COP. Other attributes such as location of hotspots and pressure impulses can be used to augment the biofeedback signals. The sensor system may be used in other sensing applications such as measuring impacts in sports or pressure points in patients confined to sitting or prone positions.
