摘要： A fluid flow velocity measuring device is shown. In the preferred and illustrated embodiment, an elongate body receives a removable spinner cartridge assembly. The assembly is formed of an elongate sleeve surrounding a rotating shaft supported by bearing assemblies at opposite ends of the shaft. The shaft supports a spinner. Particular sizes of spinners are calibrated to a particular flow velocity ranges and density of material. The insert is held in position by a compressed spring behind the insert so that fluid flow is directed from an inlet port in the tool adjacent a petal basket, along an axial passage in the tool, and through the spinner and out through an outlet port.

The angle sensors are operable to be biased to positional settings associated with a desired pointing direction of the energy beam. A secondary optical element is arranged in the optical path and translated along three orthogonal axes. A plurality of steering mirrors arranged between the optical reference source and the secondary optical element is configured to be tilted in response to a control signal. A controller auto-aligns the telescope by at least translating the secondary optical element and tilting the steering mirrors via the control signal using at least inputs from the plurality of angle sensors.

摘要： A high-energy beam is precompensated by a process including receiving a high-energy beam from a source and energy from a target. The target energy includes wavefront aberrations related to atmospheric and other external disturbances encountered along a distance separating the target. A correction signal is determined responsive to the high-energy beam and the target energy. The correction signal is also configured to pre-compensate for wavefront aberrations related to the atmospheric and other external disturbances and to cancel aberrations introduced by the adaptive optics techniques. A wavefront of the outcoupled high-energy beam is adjusted responsive to the determined correction signal. A beam control system includes three adaptive optics servo loops and an aperture-sharing element. The arrangement is adapted to self-cancel internal optical-path-difference errors in the outcoupled beam and to pre-compensate the outcoupled beam according to a conjugate of the wavefront aberrations related to atmospheric and other external disturbances.

摘要： A beam control system and method. The system includes an illuminator for providing a first beam of electromagnetic energy at a first wavelength; a source for providing a second beam of electromagnetic energy at a second wavelength; and an arrangement for compensating wavefront errors in the second beam using a bias representative of a comparison between the first wavelength and the second wavelength.

In the disclosed application, a target wavefront sensor is included and the laser is a high-energy laser beam. The wavefront errors include a chromatic aberration and the errors are compensated using a deformable mirror and a correction algorithm executed by an adaptive optics processor. In one alternative embodiment, the errors are compensated using an optical aberration corrector. The aberration corrector may be a holographic optical element or other suitable device. In another alternative embodiment, the errors are corrected with the above embodiment in combination with the use of “woofer” and “tweeter” correcting elements with the woofer being a long stroke low frequency element and the tweeter being a short stroke high frequency element.
