Patent number: 11181491Abstract: Aspects of the disclosure are directed to an analysis of a material of a component. A radiation source is activated to transmit radiation to the component. A beam pattern is obtained based on the component interfering with the radiation. The beam pattern is compared to a reference beam pattern. An anomaly is detected to exist in the material when the comparison indicates a deviation between the beam pattern and the reference beam pattern.Type: GrantFiled: April 9, 2018Date of Patent: November 23, 2021Assignee: Raytheon Technologies CorporationInventors: Iuliana Cernatescu, David U.

Patent number: 10458929Abstract: A system for the x-ray topography analysis of a sample, comprising in combination, a goniometer having a base, a tube arm rotatably associated with the base, a detector arm rotatably associated with the base, and a sample stage operatively associated with the base. The system also includes an x-ray source operatively coupled with the tube arm and is capable of emitting a non-collimated beam of x-rays. A collimator is operatively associated with the x-ray source and converts the non-collimated beam of x-rays into a collimated beam of x-rays having a quasi-rectangular shape with a divergence less than three degrees in all directions. A detector operatively coupled to the detector arm.Type: GrantFiled: November 8, 2018Date of Patent: October 29, 2019Assignee: UNITED TECHNOLOGIES CORPORATIONInventors: Iuliana Cernatescu, Vasisht Venkatesh, David Ulrich Furrer
