Abstract
An apparatus and method to align ceramic honeycomb bodies. The apparatus includes a light source to direct light toward a first end of a ceramic honeycomb body, a lens to receive at least a portion of the light directed to the first end of the ceramic honeycomb body, an imaging device to capture an image of the received light, wherein the image comprises a portion of a side surface of the honeycomb body. The apparatus comprises a controller configured to receive the captured image, to analyze the captured image based on the portion of the side surface, to adjust the ceramic honeycomb body and/or the lens based on the analysis to align the ceramic honeycomb body and the lens optical axis.
