摘要： A computer-implemented method of transmitting through a disordered medium from a transmitter to a receiver an image represented as input coherent electromagnetic radiation, the disordered medium having a transmission matrix comprising a plurality of complex-valued transmission constants that relate said input coherent electromagnetic radiation to output electromagnetic radiation at said receiver, which method comprises the steps of: performing a characterising process on said disordered medium to determine said transmission matrix; using said transmitter to transmit said image through said disordered medium; performing a reconstruction process using said transmission matrix to generate a reconstructed image from the output electromagnetic radiation at said receiver; wherein in said characterisation process the step of determining said transmission matrix comprises: determining said complex-valued transmission constants as real-valued transmission constants by using an approximately linear relationship between said input electromagnetic radiation and said output electromagnetic radiation; and using said real-valued transmission constants to generate and store a version of the transmission matrix; and said reconstruction process comprises the steps of: generating an output signal comprising intensity or amplitude values of said output electromagnetic radiation; generating said reconstructed image by combining said output signal and said version of the transmission matrix in a way that effects a matrix multiplication of an inverse of said transmission matrix and said output signal; and outputting said reconstructed image from said receiver.

摘要： An optical element (100) is provided comprising a first surface (102) for emitting and/or receiving electromagnetic radiation, the first surface being arranged for optically coupling to, or being optically coupled to, a portion of an optical fibre (104) having an axis. The optical element (100) comprising a second surface (106) positioned for emitting and/or receiving electromagnetic radiation in a direction transversal to the axis of the optical fibre (104), wherein the optical element (100) has a first focal length for electromagnetic radiation emitted and/or received by an inner portion of the second surface (106) and a second focal length for electromagnetic radiation emitted and/or received by an outer portion of the second surface (106), the first and second focal lengths being different focal lengths. A method of forming an optical device comprising the optical element (100) and further comprising an optical fibre coupled to the optical element is also provided.

摘要： The present invention relates to Fiber Feedback (FFB) technology, and provides a method and system for estimating distance between a fiber end and a target. The method includes illuminating, by a Light Emitting, Transmitting and Detecting (LETD) system, the target with laser light of different wavelengths having low and high water absorption coefficients, using different laser light sources, as well as receiving a returned signal corresponding to the incident laser light of different wavelengths, and detecting the returned signal to measure intensity values of the returned signal of a specific wavelength. Using the measured intensity values, a processing unit may estimate distance between the fiber end and the target. The present invention enables accurate estimation of distance between a fiber end and a target, and also provides a robust distance estimation technique which is compatible with different types of targets.

摘要： Die Erfindung betrifft ein Boroskop (1), insbesondere für die Boroskopie der Brennkammern (58) von Flugzeugtriebwerken (50), sowie eine Anordnung (31) umfassend ein Boroskop (1). Das Boroskop (1) umfasst eine elektronische Bilderfassungseinheit (20) mit wenigstens einem Bilderfassungssensor (22, 23) mit einem Aufnahmekegel am ersten Ende (4) eines Schafts (3) mit einer Schaftachse (3'), durch den Daten- und Versorgungsleitungen (21) für die Bilderfassungseinheit (20) geführt sind, wobei die Bilderfassungseinheit (20) an einem drehbar um die Schaftachse (3') am ersten Ende (4) befestigten Rotationskopf (10) derart angeordnet ist, dass die Achse (22', 23') des Aufnahmekegels nicht-parallel zur Schaftachse (3') am ersten Ende (4) verläuft und durch Drehung des Rotationskopfes (10) ein Rundbild aufnehmbar ist. Die Anordnung (30) umfasst ein erfindungsgemäßes Boroskop (1) und eine Steuer- und Auswerteeinheit (31), die zum Steuern der Rotationsbewegung des Rotationskopfes (10) und der Bilderfassungseinheit (20), sowie zum Zusammenfügen der von dem wenigstens Bilderfassungssensor (22, 23) erfassten Bilddaten zu einem Rundbild ausgebildet ist.
