MEASURING DEFLECTION TO DETERMINE A CHARACTERISTIC OF A LAYERED-MATERIAL STRIP
20210131985 · 2021-05-06 ·

Disclosed are methods that, by not physically touching a material being measured, can measure the material's differential response quite accurately. A collimated light shines on the material under test is reflected off it, and is then captured by a device that records the position where the reflected light is captured. This process is done both before and after the material is processed in some way (e.g., by applying a coat of paint). The change in position where the reflected light is captured is used in calculating the deflection of the material as induced by the process. This measured induced deflection is then used to accurately determinate the stress introduced into the material by the process. Other characteristics of the material under test, such as aspects of the material composition of a bi-metallic strip, for example, may also be determined from a deflection measurement.

10935502 · 2021-03-02 · ·

A method for detecting inconsistencies in an assembly using an energy source and an imaging device is disclosed. An energy source directs energy through first scanning mirrors toward a surface of the laminated composite assembly raising an energy level of an inspection area. An imaging device directs a view through second scanning mirrors toward the inspection area and the imaging device detects a rate of change in energy at the surface of the laminated composite. Movement of the first scanning mirrors is synchronized with movement of the second scanning mirrors for directing a view of the imaging device to the inspection area after the energy level of the area of the surface has been raised. The imaging device detects dissipation of energy at the area of the surface being inspected and identifies inconsistencies associated defects in the assembly.

INSPECTION OF BONDING QUALITY OF TRANSPARENT MATERIALS USING OPTICAL COHERENCE TOMOGRAPHY

An optical coherence tomography (OCT) system (63) is used to inspect bonding points (66A, 66B, 66C) sandwiched between two materials (layers 62, 64 of e.g. displays). The OCT differentiates between a bonding point, e.g. a weld, and air gaps between the two materials. The bonding points are identified as breaks in the air gap between the materials. By extracting various physical characteristics of the bonding points and the gap between the two materials, the present system determines whether the bonding is faulty.
