Abstract

The invention belongs to the technical field of optical coherence tomography, and particularly relates to a sample arm light path structure and an OCT imaging system. The sample arm light path structure comprises sample scanning probes. The sample scanning probe comprises a scanning galvanometer, which is used for incidence of a first light beam, reflects the first light beam to a to-be-detected sample, and receives the first light beam reflected back from the to-be-detected sample; and a light beam control mechanism, which is arranged on the propagation light path of the first light beam andhas a first control state and a second control state. The light beam control mechanism enables the first light beam to be reflected to the to-be-detected sample through the scanning galvanometer underthe first control state, and limits the first light beam to be reflected to the to-be-detected sample through the scanning galvanometer under the second control state. There are multiple sample scanning probes, and at most one light beam control mechanism is in the first control state; and the plurality of scanning probes share one set of broadband light source and one set of spectrum analyzer, so that the problem that the cost is too high because the plurality of scanning probes are arranged in a time division multiplexing occasion is solved.

Description

Technical field [0001] The invention belongs to the technical field of optical coherence tomography, and particularly relates to a sample arm optical path structure and an OCT imaging system. Background technique [0002] Capsules are common medicines in medicine. For a capsule with a liquid sealed inside, if the sealing is poor, the capsule will fail due to liquid leakage; while a capsule with a solid inside, the internal medicine may be oxidized and fail due to poor sealing, so the sealing of the capsule It directly affects the shelf life of the capsule. [0003] At present, in the field of medical preparation, OCT, as a non-destructive testing technology, can detect the fault condition inside the capsule and realize the detection of the capsule's tightness. On the one hand, this kind of detection finds poorly sealed capsules and removes them, improving the yield of capsule preparation; on the other hand, it can monitor the production status of the preparation equipment.
