Title:
METHOD AND APPARATUS FOR INSPECTING HONEYCOMB STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2012/039480
Kind Code:
A1
Abstract:
Provided is a method for inspecting a honeycomb structure, which is provided with: a step of obtaining a computed tomography image of a first cross-section, which is at a distance (Z1) from one end surface (112d) of a honeycomb structure (100), and a computed tomography image of a second cross-section at a distance (Z2) from the one end surface (112d) of the honeycomb structure, said distance (Z2) being longer than the distance (Z1); a step of determining, on the basis of the computed tomography image of the first cross-section, presence/absence of a sealing portion (114) in at least one channel among a plurality of channels; a step of determining, on the basis of the computed tomography image of the second cross-section, presence/absence of the sealing portion at least in the one channel; and a step of determining the length of the sealing portion on the basis of the result of determination of presence/absence of the sealing portion, said determination having been made on the basis of the computed tomography image of the first cross-section, and the result of determination of presence/absence of the sealing portion, said determination having been made on the basis of the computed tomography image of the second cross-section.
