A system and a method for non-destructive characterizations of objects using Laser Acoustic Resonance Spectroscopy (LARS)-based diagnostic techniques are provided. The system includes using a laser doppler vibrometer to measure vibrational responses of objects. The method includes measuring vibrational frequency responses of a first object and a second object, performing a spectra analysis of the vibrational frequency responses, determining a frequency shift based on the spectra analysis, and indicating a difference between the first object and the second object or a presence of a defect in the second object if the determined frequency shift exceeds a predefined threshold value. The difference between the first object and the second object may indicate the presence of a void, a crack, or a plurality of pores in the second object, or can be used for validating or authenticating the second object as a defective or counterfeit item, in various embodiments.

Regarding to a fiber-reinforced material formed by deforming a reinforcing material composed of a plurality of fiber layers from an initial shape and molding into a predetermined shape, an identification device, an identification method, and an identification program generate a first data in which a physical quantity distribution inside the fiber-reinforced material is mapped to the initial shape, perform binarization of the first data to generate a second data in which a label identifying the fiber layer is mapped to the initial shape, and map the second data to a predetermined shape, based on a deformation data.

An apparatus for material testing of a specimen. The apparatus-includes a specimen holder for holding a specimen to be tested, a rod arrangement for moving in direction to the specimen holder for transmitting a mechanical load to the specimen, an actuator for moving at least one of the rod arrangement and the specimen holder with respect to each other along a horizontal impact direction, and a supporting base, onto which the specimen holder, the rod arrangement and the actuator are mounted. A specimen holder arrangement is detachably coupled to a holder accommodation section of the supporting base.

System and method that includes: projecting a dynamic lighting pattern from a controlled lighting device towards a manufactured object; capturing a light response of the object, over an inspection period, to the dynamic lighting pattern and generating a set of image frames representing the captured lighting response; processing the set of image frames to generate an intensity image that is based on intensity information across a plurality of the image frames; assigning a quality label based on the generated intensity image.

The present disclosure relates to a system and a non-transitory computer-readable medium for estimating the height of foreign matter, etc. adhering to a sample. In order to achieve the abovementioned purpose, proposed is a system, etc. in which data acquired by a charged particle beam device or features extracted from the data are input to a learning model, which is provided with, in an intermediate layer thereof, a parameter learned using teacher data having data acquired by the charged particle beam device or features extracted from the data as inputs and having the heights or depths of the structures of samples or of foreign matter on the samples as outputs, and height or depth information is output.

A recording system for the automated documentation of defects in semi-finished products, includes at least one measuring device configured to record at least one measured value of a semi-finished product that is processed in the manufacturing plant, and a data processing device, which is connected to the at least one measuring device and which receives the at least one measured value. The data processing device includes: a database in which database entries for documenting defects in the semi-finished product can be saved; a comparison device, which is configured to compare the at least one measured value with predefined range limits and to save the at least one measured value lying outside the range limits in a database entry; and a damage recording device configured to record data on the extent of the damage caused by the defect if the at least one measured value is outside the range limits.
