Abstract: Defect detection systems include at least one nozzle for delivering a CO2 particulate fluid to an inlet end of a plugged honeycomb body. Defects in the honeycomb, if any, are determined by monitoring CO2 particulate flow at the outlet end of the honeycomb body. Methods for detecting defects in plugged honeycomb bodies are also disclosed.

Abstract: A method of inspecting defects of a transparent substrate may include: illuminating a transparent substrate; calculating an incidence angle range of light so that a first region where the light meets a first surface of the transparent substrate and a second region where light meets a second surface being opposite the first surface of the transparent substrate do not overlap each other; adjusting an incidence angle according to the incidence angle range; adjusting a position of a first detector so that a first field-of-view of the first detector covers the first region and does not cover the second region; adjusting a position of a second detector so that a second field-of-view of the second detector covers the second region and does not cover the first region; and obtaining a first image of the first region and a second image of the second region from the first and second detector, respectively.

Abstract: Various aspects of the present disclosure relate to a method of cleaning a glass substrate. The method includes contacting the glass substrate with a cleaning agent for a predetermined amount of time. The cleaning agent includes a substance having a sublimation point in a range of from about −90° C. to about −70° C. and the cleaning agent is dispersed in a gas carrier.

Abstract: A method for inspecting a transparent workpiece comprises: directing light from an illumination source onto a plurality of defects formed in the transparent workpiece, wherein the plurality of defects extends in a defect direction, wherein the transparent workpiece comprises a first surface and a second surface; detecting a scattering image signal from light scattered by the plurality of defects using an imaging system, wherein an imaging axis of the imaging system extends at a non-zero imaging angle relative to the defect direction, wherein entireties of at least a subset of the plurality of defects are within a depth of field of the imaging system; and generating a three-dimensional image of at least one of the plurality of defects based on the scattering signal.

Abstract: A method of inspecting defects on a transparent substrate may include: selecting a gradient of an illumination optical system so that light incident on the transparent substrate has a first angle; selecting a gradient of a detection optical system so that an optical axis of the detection optical system located over the transparent substrate has a second angle, which is equal to or less than the first angle; adjusting a position of at least one of the illumination optical system, the transparent substrate, and the detection optical system so that a field-of-view of the detection optical system covers a first region where the light meets a first surface of the transparent substrate and does not cover a second region where light meets a second surface of the transparent substrate, the second surface being opposite to the first surface; illuminating the transparent substrate; and detecting light scattered from the transparent substrate.
