An improved Raman microspectrometer system extends the optical reach and analysis range of an existing Raman microspectrometer to allow analysis and/or repair of an oversized sample. The improved Raman microspectrometer system includes an extender for extending the optical reach of the existing microspectrometer and a supplemental stage which extends the analysis range of the existing microspectrometer by providing travel capabilities for non-destructive analysis of an entire oversized sample. Such an arrangement decreases manufacturing costs associated with testing oversized samples such as mammography panels, enabling analysis and/or repair to be performed without destruction.

The invention discloses a multifunctional multi-channel ion source for a mass spectrometer and a mass spectrum analysis method for trace components in an original sample. The ion source comprises a sample ionization area consisting of a high-voltage power supply, a plurality of nozzles and a sample disc, and at least two channels, wherein sample flow injected from the second channel collides with reagent ions injected from the first channel to form sample ions, or the reagent ions injected from the first channel collide with a sample in the sample disc to ionize the sample, and the sample is introduced into an inlet capillary of the mass spectrometer for mass spectrum analysis. The multi-channel ion source can be connected with common mass spectrometers such as LCQ, LTQ and TSQ, so that the functions of the common mass spectrometers are upgraded and powerful to rapidly and sensitively measure the gas, liquid, solid and colloid samples in the mass spectrum analysis method, and the multifunctional multi-channel ion source can be applied to in-situ, real-time, online and nondestructive analysis in the industrial or environmental process.

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.

The invention discloses a method for analyzing the electric leakage failure between the bit lines of a flash memory chip, relating to the field of chip failure analysis. With a nondestructive analysis process, the FIB segmentation process is combined with a nanoscale probe measuring process, the failed plug is directly positioned without damaging all materials of the front-end process, the bridges (for example, the bridge at the top, middle or any other position of the plug) at different positions of the plug can be detected, and a relatively good TEM sample can be obtained so as to facilitate subsequent precise observation of TEM; and therefore, the time for failure analysis, the process cost and the like can be greatly reduced while the reliability of the failure analysis is effectively improved.

Systems and methods for an in situ, non destructive analysis of organic or inorganic material are disclosed. In one respect, a particle induced x-ray emission system, having a footprint of less than one square meter, includes a sample holder supporting a sample, a source holder supporting one or more radioactive source and a detector. A radioactive transmission from the one or more radioactive source to the sample results in a fluorescent emission of the sample and collected by the detector. In one respect, fluorescent emission may be used to determine elements found in the sample. Additionally, the amounts of each of the determined elements found in the sample may also be determined.

There is provided a nondestructive analysis for a periodic structure. In the method, a virtual periodic structure is set and divided into a plurality of layers. By utilizing the Lippmann-Schwinger equation with an M-th order interpolation, physical properties related to reflectivity or transmittance of the virtual periodic structure are calculated. An M-th order interpolation formula employed in discretization of the Lippmann-Schwinger equation leads to an accurate and rapid calculation of the physical properties of the periodic structure.

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.
