    Abstract: An optical network including an input to receive from an optical network light comprising plural wavelength components. An optical wavelength selective filter, optically connected to the input, extracts a first wavelength component of the plural wavelength components from the light, thereby providing a first optical signal including the first wavelength component and a second optical signal including a remainder of the plural wavelength components a light emitter to provide a modulated broadband optical signal. A first output, optically connected to the optical wavelength selective filter, receives a first portion of the second optical signal for transmission to a light detector and a second output, optically connected to optical wavelength selective filter, receives a second portion of the second optical signal for transmission to the optical network.

    Abstract: A method of measuring a surface of a liquid, the surface of the liquid having an edge which contacts a solid structure and an interior area which does not contact the solid structure. The surface of the liquid and the solid structure are illuminated with a pattern so that an upper part of the pattern is projected onto the solid structure to form an upper projected pattern and a lower part of the pattern is projected onto the interior area of the surface of the liquid to form a lower projected pattern. An image of the upper projected pattern is acquired and analysed to determine a height of the edge of the surface of the liquid. An image of the lower projected pattern is acquired and analysed to determine a characteristic of the interior area of the surface of the liquid.

    Abstract: A device for use in determining the rotational speed of a body. The device includes a sensor for detecting the strength of a magnetic field, and a body that is rotatable relative to the sensor about an axis. The body includes circumferentially spaced magnetic regions. The device is arranged so that, during rotation of the body relative to the sensor, the maximum strength detectable by the sensor of a first magnetic field of a first of the magnetic regions is different to the maximum strength detectable by the sensor of a second magnetic field of a second of the magnetic regions.
