摘要： Spectral interferometric systems and methods to characterize lateral and angular spatial chirp to optimize intensity localization in spatio-temporally focused ultrafast beams are described. Interference between two spatially sheared beams in an interferometer leads to straight fringes if the wavefronts are curved. To produce reference fringes, one arm relative to another is delayed in order to measure fringe rotation in the spatially resolved spectral interferogram. Utilizing Fourier analysis, frequency-resolved divergence is obtained. In another arrangement, one beam relative to the other is spatially flipped, which allows the frequency-dependent beamlet direction (angular spatial chirp) to be measured. Blocking one beam shows the spatial variation of the beamlet position with frequency (i.e., the lateral spatial chirp).

摘要： A state visualizer according to one aspect of the present disclosure includes an optical member including a fixed part that has a fixed relative positional relationship with an object to be measured and a movable part that is movably supported by the fixed part and keeps a constant angle with respect to a gravity direction, the optical member retroreflecting a light or an electromagnetic wave in a case where the fixed part and the movable part are in a predetermined positional relationship. The optical member changes an intensity of the light or the electromagnetic wave reflected in a retroreflection direction in accordance with a change of a relative positional relationship between the fixed part and the movable part.

摘要： An integrated optical assembly is provided, with enhancements that are particularly useful when the integrated optical assembly forms part of a laser radar system. The integrated optical assembly produces a reference beam that is related to the optical characteristics of a scanning reflector, or to changes in position or orientation of the scanning reflector relative to a source. Thus, if the scanning reflector orientation were to shift from its intended orientation (due e.g. to thermal expansion) or if characteristics of the scanning reflector (e.g. the index of refraction of the scanning reflector) were to change on account of temperature changes, the reference beam can be used to provide data that can be used to account for such changes. In addition, if the scanning reflector were to be positioned in an orientation other than the orientation desired, the reference beam can be used in identifying and correcting that positioning.

摘要： Systems, methods, and devices may provide an optical scheme that achieves simultaneous wavelength channels and maintains the resolution and luminosity of an etalon. Various embodiments may provide a method to optically recirculate the light reflected from the etalon back through the same etalon at new angles. Various embodiments create an etalon spectrometer based on angular dispersion without moving parts and without losing the light that is not initially transmitted. Various embodiments may provide a spectrally-resolved receiver and/or transmitter. Various embodiments may provide a system including a retro-reflector, a detector or transmitter array, and an etalon disposed between the retro-reflector and the detector or transmitter array, wherein the retro-reflector is configured to redirect light reflected by the etalon back to the etalon at a different angle of incidence than an original angle of incidence on the etalon of the light reflected by the etalon.

摘要： Reflective target for surveying instruments having a plurality of planar reflective sections arranged to form a shape having a target axis. Each reflective section includes a plurality of prisms, each prism constituted by a corner cube having three surfaces oriented perpendicular to one another and forming a base for receiving incident light, and each of the prisms is oriented such that a common edge formed by two of the three surfaces of the prism is oriented such that the common edge and the target axis or a line parallel to the target axis lie in a common plane.

摘要： Interrogation optical beams are focused or otherwise shaped for delivery to a target that includes one or more tooling balls so as to have a beam radius of curvature corresponding to a tooling ball radius. Focus values can be stored in a look-up table and can include two beam focus conditions that produce a selected beam focus. The two beam focus conditions are associated with a common beam curvature. The focus conditions are associated with beam curvatures within and without a Rayleigh range from a beam waist.

摘要： A beam brush includes one lens fixed for receiving a laser beam propagating along a first beam axis, a retroreflector positioned for redirecting the laser beam onto a second beam axis through a change in beam path length, and a second lens transmitting the redirected beam. The retroreflector is rotatable about an offset axis and has its angle of rotation controlled for affecting a change in beam path length. The angle of rotation resulting in the path length change is selected for providing a focus or divergence of the reflected beam transmitted through the second lens. Such a system is useful as a Z-axis focusing device operable an X-Y scanner located downstream the modified beam.
