A system comprises a medical device configured to be positioned at least partially within a scattering medium, the medical device comprising at least one optical fibre or other waveguide having a plurality of light-emitting regions arranged along at least part of the length of the at least one optical fibre or other waveguide; a pulsed light source configured to transmit pulsed light into a proximal end of the at least one optical fibre or other waveguide, such that the pulsed light is guided along the at least one optical fibre or other waveguide to the light-emitting regions and emitted by the light-emitting regions into the scattering medium; at least one detector configured to receive photons of the pulsed light that have passed through the scattering medium; and a processor configured to: select signals corresponding to at least some of the received photons; determine a respective location of each of the light-emitting regions based on the selected signals; and determine a path of at least part of the medical device based on the determined locations.

Imaging system and method

A system comprises a waveguide apparatus comprising a plurality of input waveguides, a multimode waveguide, and a guided-wave transition coupling the plurality of input waveguides to the multimode waveguide. The system further comprises at least one light source configured to excite in turn each of a plurality of the input waveguides, or each of a plurality of combinations of the input waveguides, thereby generating a plurality of different light patterns in turn at an output of the waveguide apparatus. The waveguide apparatus is configured to direct each of the plurality of different light patterns to a target region. The system further comprises at least one detector configured to detect light transmitted, reflected or emitted from the target region in response to each of the different light patterns, and to output signals representing the detected light.

Optical system and method

An optical device includes a unitary substrate of optically transparent material. The unitary substrate has formed therein at least one collection lens and channel, the channel for receiving an optical fibre and arranged to align the optical fibre inserted therein such that the collection lens couples light collected by the collection lens into the optical fibre.

Direct laser writing and chemical etching and optical devices

A method of forming an optical device in a body (), comprises performing a plurality of laser scans () to form the optical device, each scan comprising relative movement of a laser beam and the body thereby to scan the laser beam along a respective path () through the body to alter the refractive index of material of that path, wherein the paths are arranged to provide in combination a route for propagation of light through the optical device in operation that is larger in a direction substantially perpendicular to the route for propagation of light than any one of the paths individually.

Method of forming an optical device by laser scanning

A measurement scale device includes at least one scale marking, wherein the or each scale marking includes at least one periodic nanostructure that represents scale device information.

Measurement scale with periodic nanostructure

An optical adapter that is arranged to connect two or more optical devices that have different connector layouts, the optical adapter comprising a material through which a plurality of waveguides is formed, the waveguides defining a first connector configuration at one end or face of the material and a second connector configuration at another, or same end or face of the material.
