摘要： A cantilever for the use in atomic force microscopy includes a cantilever arm having a fixed end being attached to a base member and a free end where the cantilever arm has a first shape and an axis of torsion associated with the first shape, and a probe tip projecting from the cantilever arm near the free end where the probe tip is positioned in an offset displacement from the axis of torsion. Alternately, the cantilever arm has a first shape selected to tune a torsional resonance frequency of a selected torsional mode or the fundamental flexural resonance frequency of the fundamental mode so that the torsional resonance frequency and the fundamental flexural resonance frequency has an integer ratio. In this manner, the torsional motion of the torsional harmonic cantilever at that harmonic frequency will be largely enhanced by the corresponding torsional resonance.

摘要： One embodiment of the present invention provides a spatial light phase modulator, which can perform piecewise linear phase modulation of a light beam. This spatial light phase modulator includes an array of movable micromirrors and an array of actuators. Each actuator of the array of actuators is movably coupled to one micromirror of the array of movable micromirrors and can move the micromirror both vertically and rotationally. Additionally, the present invention provides an optical function generator that is a femtosecond pulse shaper. This optical function generator includes a diffraction grating that disperses an input pulse into a dispersed spectrum, a lens assembly to focus the dispersed spectrum onto a micromirror array, and the micromirror array to provide spatial filtering to the dispersed spectrum to provide the filtered spectrum.

摘要： A modulator for modulating incident rays of light, the modulator having a plurality of equally spaced apart elements, each of which includes a light reflective planar surface. The elements are arranged parallel to each other with their light reflective surfaces parallel to each other. The modulator includes means for supporting elements in relation to one another and means for moving particular ones of the elements relative to others so that the moved elements transit between a first configuration wherein the modulator acts to reflect the incident rays of light as a plane mirror, and a second configuration wherein the modulator diffracts the light reflected therefrom. In operation, the light reflective surfaces of the elements remain parallel to each other in both the first and the second configurations. The perpendicular spacing between the reflective surfaces of respective elements is equal to m/4 times the wavelength of the incident rays of light, wherein m=an even whole number or zero when the elements are in the first configuration and m=an odd whole number when the elements are in the second configuration.
