InactiveUS6624885B1Quickly and accurately and efficiently inspectedOptically investigating flaws/contaminationLaser beam welding apparatusNon destructiveAerosolization
A method for inspecting small holes in a material is disclosed. The method comprises directing a light source through the holes in the material, and then focusing the light passing through the material onto a CCD detector. The focusing techniques allow for a reduction in the size of the image which must be inspected, thereby increasing sample throughput, while still allowing for detailed inspection of the hole number and quality. Methods of producing an aerosolization container and device comprising membranes which pass such an inspection are also provided.

Non-Destructive Analysis of an Object
A computed tomography (CT) scanning system performs non-destructive analysis of an object. The CT scanning system generates a series of two-dimensional images of the object from different angles as the object rotates. The CT scanning system uses the generated two-dimensional images to reconstruct three-dimensional images of the object. By displaying several reconstructed three-dimensional images over time, the CT scanning system generates a four-dimensional representation of the object.

A system and methods by which the state or condition of an object may be determined through the analysis of spectral bands. One embodiment of the present invention automatically detects a first spectral band having an absorption that is highly sensitive to the color of the object, such as that produced through a colorant or a pigment of interest. The embodiment then may automatically detect a second spectral band having absorption sensitive to color resulting from other colorants or pigments other than the pigment of interest. A third spectral band may also be automatically detected that is sensitive to reflective differences caused by variation in conditions. Subtracting the absorption in the first band by the second band and multiplying the result by the amount of light reflected in the third band results in the index. The index can be highly correlated with the concentration of the colorant of interest.

Nondestructive analysis method, nondestructive analysis device, and specific object analyzed by the method/device
InactiveUS20080298551A1Handling using diffraction/refraction/reflectionMaterial analysis by transmitting radiationX-rayUsage analysis
Non-destructive analysis is carried out by irradiating an object with X-rays, for example, so that the X-rays from the object are incident on an analyzer crystal. The analyzer crystal can be of a transmission-type or a reflection-type. A pre-crystal device is used to make the radiation monochromated and parallelized. Atomic lattice planes of the pre-crystal device are approximately parallel with the atomic lattice planes of the analyzer crystal so as to use the angular analysis capability of the analyzer crystal. The thickness of the analyzer crystal is fixed. For example, for a transmission-type analyzer crystal, the thickness is such that irradiation with monochromatic parallel X-rays in the absence of the object results in a condition in which either one of (a) X-rays along a forward diffraction direction and (b) X-rays along a diffraction direction obtained by dynamical diffraction by the transmission type analyzer crystal have an intensity of nearly zero as compared to the intensity of the other with respect to the monochromatic parallel X-rays. At least one or both of an X-ray dark-field image and an X-ray bright-field are obtained.

PendingCN111968768AImprove parallelismEnsure safe and efficient developmentNuclear energy generationNuclear monitoringNeutron moderatorBurnup
The invention discloses a nuclear fuel burnup depth measuring device based on active neutron space intensity distribution and a measuring method thereof. The measuring device comprises a compact D-D neutron source, a neutron moderator and a gamma shielding body which wrap the D-D neutron source in sequence, a conical neutron collimation hole channel formed in the neutron moderator, and a thermal neutron image detector system connected with the conical neutron collimation hole channel. The conical neutron collimation pore channel is arranged at a certain distance above the compact D-D neutron source and is used for obtaining quasi-parallel neutron beams. Because the thermal neutrons and different elements in the nuclear fuel have different reaction sections, the neutron fluxes of the conical neutron collimation pore channels penetrating through the nuclear fuel element sample are different in space, and the burnup depth space distribution and the average burnup of the nuclear fuel element are measured according to the established response model of the thermal neutron transmission intensity and the fuel burnup. The method belongs to a novel nuclear fuel burnup non-destructive analysis technology, and has the characteristics of rapidness, accuracy, no damage and good spatial resolution.

Disclosed herein are a method, apparatus, and software for passive, non-destructive assay of holdup deposits in nuclear piping by in-pipe apparatus. A detector deployed within a pipe is collimated to observe radiation impinging radially inward from decay of deposits that lie on the pipe wall. A radiation detector is centered in the pipe and collimated by a pair of coaxial shielding discs disposed equidistant from the detector. This arrangement causes radiation from a truncated cylinder of pipe deposit within a field of regard to impinge on the detector, while precluding radiation emanating from pipe walls beyond the field of regard from reaching the detector. Hence, observations are unique to a known cylindrical length of pipe. The detector assembly is translated through pipes by an autonomous mobile robotic apparatus. Computer software controls the robotic apparatus, logs data, and post-processes to assay deposits.
