    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 atomic force microscope based apparatus for examining a sample includes a cantilever having a cantilever arm and a probe tip where the probe tip is offset laterally from a longitudinal axis of torsion of the cantilever arm, an oscillator that drives the cantilever into oscillation in a flexural mode to cause the probe tip to repeatedly interact with the sample where the tip-sample interaction of the laterally offset probe tip excites torsional motion of the cantilever, and a detection system that detects torsional motion of the cantilever in response to the tip-sample interaction.

    摘要： A tunable laser comprises multiple reflectors defining a resonant cavity, and an optical gain medium positioned within the resonant cavity. One of the reflectors is a programmable micromirror array that acts as a tunable blazed diffraction grating providing continuous tuning of a single resonant mode over a wavelength gain region of the gain medium. The continuous tuning is provided by altering the micromirror array to shift, in synchrony, a resonant mode wavelength of the resonant cavity and a reflection filtering peak of the array. The array comprises a plurality of micromirror elements that can be controlled to independently move in a direction perpendicular to the plane of the array. In one embodiment, each element has a V-shaped movable mirror. In another embodiment, each element has a flat or slightly-tilted horizontal mirror and a vertical or nearly-vertical mirror orthogonal to the horizontal mirror producing a corner-cube-like reflection.

    摘要： A reconfigurable optical device capable of filtering, multiplexing, and spectrometry, among other functions. The device has an array of micromirrors disposed under a floating reflector that is partially reflecting. The floating reflector is spaced apart from the micromirrors a certain distance. The micromirrors are each capable of independent vertical motion, and, optionally, tilting motion. In use, light is projected at an oblique angle into the space between the micromirrors. Each reflection from the floating reflector produces an emergent beam from the floating reflector. The emergent light beams are combined with a lens. As a direct result of this structure, different wavelengths are focused to different points in the focal plane of the lens. The focal point positions of the different wavelengths can be moved by manipulating the micromirrors. This allows for reconfigurable filtering, spectrometry, and multiplexing, among other applications.
