摘要:
The invention concerns a device (1) for testing at least one sample by optical detection of luminescence, comprising a site for receiving (3) the sample, said site being arranged in such a way that the sample can receive a luminescence excitation and emit a luminescence light in an optical guiding plane (2) of the device, the device further comprising collection means (7) optically connected to the optical guiding plane (2) to receive the luminescence light. The device further comprises means that make it possible to send back towards the collection means (4) a part of the luminescence light emitted in the optical guiding plane and not directly collected by the collection means.

A positioning system for an optical microstructure (64) in a devise (6) operating under the action of a control means includes a flexible element (63) supporting the optical microstructure and connected to the device. The orientation of the flexible element with respect to the device can be varied under the action of control means in order to put the optical microstructure (64) into at least one determined position. The flexible element is immobilized with respect to the device in order to hold the optical microstructure (64) in the determined position when the control means no longer act.

摘要:
An optomechanical sensor for measuring or detecting an acceleration or a vibration in at least one direction. The sensor has a frame, and a flexible beam having two ends. A first end is attached to the frame and a second end is mobile in the at least one direction, in response to an acceleration movement of the frame. The flexible beam includes an optical guiding structure having an input and an output. The frame has N light collection elements, where N is an integer .gtoreq.2. The frame also includes a multi-mode coupler having an input facing the output of the optical guiding structure and N outputs, the coupler coupling an optical signal at the output of the optical guiding structure to the N light collection elements. The multi-mode coupler may also transform an input light beam having a maximum into a distribution having N maxima at the output of the coupler.
