1. An apparatus to inspect a honeycomb body, comprising:
an actuator supporting the honeycomb body, the actuator comprising a plurality of rollers including at least one roller that is driven by a motor, the plurality of rollers configured to receive and rotate the honeycomb body continuously over at least a portion of a full rotation of the honeycomb body about an axis of rotation;
a camera having a field of view encompassing an inspection region of an outer circumferential surface of the honeycomb body;
a sensor that directly measures circumferential travel along a circumference of the outer circumferential surface of the honeycomb body when the honeycomb body is rotated by the plurality of rollers, the sensor configured to trigger the camera to collect an image of the inspection region of the honeycomb body at a predetermined distance of the circumferential travel along the circumference of the outer circumferential surface based at least in part on direct measurements of the circumferential travel of the outer circumferential surface; and
a light source having an illumination area that encompasses the inspection region of the outer circumferential surface of the honeycomb body.
