摘要： A method detects a topology of a reflective surface. The method includes providing an optical fiber positioned such that light emitted from the optical fiber is reflected by at least a portion of the reflective surface. The optical fiber and the portion of the reflective surface form an optical resonator having an optical resonance with a resonance lineshape. The method further includes emitting light from the optical fiber while the optical fiber is at a plurality of positions along the reflective surface. The light emitted from the optical fiber irradiates a corresponding plurality of portions of the reflective surface. The method further includes measuring a change of the resonance lineshape due to the irradiation of the plurality of portions of the reflective surface.

摘要： An Axially Graded Index LEns (AGILE) is provided. Such optical elements can provide optical concentration in excess of the free-space brightness theorem limit, because of the increased refractive index at the output of the concentrator compared to the input. Optical contact (i.e., no intervening low index material) between the AGILE and the absorbing element (or an optical source) can be employed to ensure no loss of brightness at the interface between the AGILE and the absorbing element (or source). Although solar cell concentration is a significant application of this technology, there are various other applications, such as increasing the efficiency of optical emission, and providing transmissive optical windows that include optically cloaked regions.

摘要： According to an example embodiment of the present invention, a vibration-actuated microsurgical system includes an optical force detection arrangement having an optical encoding device configured to modulate an intensity of light in response to a displacement of a portion of the microsurgical system. Light sensing circuitry is configured to detect a force applied to the microsurgical system (e.g., and thereby to a sample) based on the intensity of light sensed from the optical encoding device. This detected force is used in controlling the application of the microsurgical system.
