Abstract

The invention is suitable for the technical field of object sealing performance detection, and provides a sealing performance detection method based on an optical coherence tomography system and a terminal. The sealing performance detection method comprises the following steps: obtaining the interference signal of the outer surface of a to-be-detected object collected by using an optical coherencetomography system; and processing the interference signal to obtain the structure image of the outer surface of the to-be-detected object, carrying out sealing performance analysis on the structure image, and judging whether the to-be-detected object is an object with a good sealing performance or not, thereby realizing sealing performance detection of the to-be-detected object.

Description

technical field [0001] The present application belongs to the technical field of object airtightness detection, and in particular relates to an optical coherence tomography system-based airtightness detection method and a terminal. Background technique [0002] Capsules in medicine are a common drug. The drug contained in the capsule can be powder, granules or liquid, and the sealing of the capsule largely determines the shelf life of the drug in the capsule. For liquid medicines, poor sealing of capsules may lead to outflow of liquid; for solid powders or granules, poor sealing may lead to oxidative deterioration of internal medicines or bacterial contamination. Therefore, the airtightness of the capsule during the preparation process is a very important indicator. [0003] During the preparation of capsules, one of the processes is: two capsule shells are nested together, and then sealed with glue around the junction of the capsule shells. However, there is currently no b...
