摘要： A three-dimensional magneto-optical trap (3D GMOT) configured to trap a cold-atom cloud is disclosed. The 3D GMOT includes a single input light beam having its direction along a first axis, an area along a second and third axis that are both normal to the first axis, and a substantially flat input light beam intensity profile extending across its area. The 3D GMOT may also include a circular, diffraction-grating surface positioned normal to the first axis and having closely adjacent grooves arranged concentrically around a gap formed in its center. The circular, diffraction-grating surface is configured to diffract first-order light beams that intersect within an intersection region that lies directly above the gap and suppresses reflections and diffractions of all other orders. The 3D GMOT may further include a quadrupole magnetic field with its magnitude being zero within the intersection region.

摘要： For textured digital elevation model generation, a method projects swath point projection coordinates of each lidar point of texel swaths into a corresponding texel swath with normalized projection coordinates. Each texel swath includes lidar points, an optical image, and swath output projection point coordinates of the lidar points into the optical image. The method generates a projection matrix including lidar point data for each lidar point of each texel swath. The method calculates enhanced lidar coordinates for each lidar point as a function of minimizing misregistration errors. In addition, the method creates enhanced output pixel coordinates for each image pixel based on the enhanced lidar coordinates for the lidar points and the associated output pixel coordinates. The method generates a textured digital elevation model based on the enhanced output pixel coordinates for each image pixel, and the enhanced lidar coordinates.

摘要： A two-axis, optical mount provides two flexural elements monolithically and homogeneously formed of a single material with, and interconnecting, three rigid segments. Between each pair of rigid segments, beginning with the first and second, a set of extensions is formed to have a cross section that permits simple, easy, independent adjustment therebetween. Likewise, a flexural element exists between the second and third rigid elements. Meanwhile, the rigid elements have section moduli sufficiently great as to be orders of magnitude larger than the flexural stiffness or section modulus of the flexural elements, thus providing flexures that operate in the elastic mode and introduce no joint type accuracy errors in adjustment.

摘要： An Optical Parametric Oscillator (OPO) capable of rapid or broadband frequency tuning by non-mechanical or mechanical means includes a resonant cavity with one or more non-linear crystals in an optical path thereof. The non-linear crystals may be driven by actuators. A pump laser pulse is transmitted into the resonant cavity with one or more seed beams having a desired wavelength. The output beam from the resonant cavity may have the same center wavelength as the one or more seed beams which may be modulated at a frequency larger than that of the pump laser, or the inverse of the pulse duration. The OPO may be used in Light Detection And Ranging (LIDAR) or Differential Absorption LIDAR (DIAL) analysis by intra-pulse modulation of output to measure absorption at multiple frequencies for each pulse of a pump beam. Sum Frequency Generator configurations may be suitable for narrow and broadband UV generation.

摘要： A spring lock includes a sinusoidal spring that has one or more crests and troughs formed along a length of the sinusoidal spring, the length extending along a sliding axis, the one or more crests and troughs forming a sinusoidal spring profile. The spring lock further includes a lock bar that has a track extending along the sliding axis, the track being configured to hold the sinusoidal spring and allow the sinusoidal spring to move along the sliding axis, the track further including one or more depressions and plateaus with the depressions and plateaus forming a lock bar profile, wherein the spring lock is locked when the sinusoidal spring profile and the lock bar profile are out-of-phase and the spring lock is unlocked when the sinusoidal spring profile and the lock bar profile are in-phase.

摘要： A two-dimensional magneto-optical trap (2D GMOT) that is configured to produce a cold-atom beam exiting the 2D GMOT is disclosed. In embodiments, the 2D GMOT is configured to feed a three-dimensional GMOT with the cold atom beam. In embodiments, the 2D GMOT includes an input light beam having its direction along a first axis, its width along a second axis, normal to the first axis, and a substantially flat input light beam intensity profile. 2D GMOT may further includes a quadrupole magnetic field with its magnitude being zero along a third axis that is centered at the center of the input light beam's width. The 2D GMOT may also include a diffraction-grating surface positioned normal to the first axis, composed of closely adjacent parallel grooves spread across the width and run parallel to the third axis.

摘要： A linear-motion stage that is angularly or radially symmetric or asymmetric, or monolithic may be used as the moving mechanism in a Fourier transform spectrometer. In embodiments, a linear-motion stage includes a base; a first multiple-arm linkage extending from the base to a first carriage attachment piece; and a second multiple-arm linkage extending from the first carriage attachment piece to the base. The first multiple-arm linkage constrains a motion of the first carriage attachment piece to motion in a first plane and the second multiple-arm linkage constrains the first carriage attachment piece to motion in a second plane, the first and second planes intersecting at a plane intersection line. The first and second multiple-arm linkages constrain the motion of the first carriage attachment piece along a carriage motion line.
