The invention relates to the technical field of optical detection, and discloses a method for detecting the collagen content of pigskin. The method establishes an initial optical profile of a pigskin sample before contacting a detection medium. And generating a special detection path aiming at the sample according to the contour, and specifying a moving track and a staying node sampled by the probe. Injecting a medium at a path starting point, and starting a synchronization mechanism to synchronize probe movement with a medium diffusion front edge; when the probe arrives at the termination node, the spectrum sequence of each node on the path is completely recorded, and the sequence comprises the dynamic characteristic absorption information of the collagen. And carrying out cross-node correlation fusion on the spectrum sequence to generate a fusion spectrum characteristic spectrum of the sample. And comparing the map with a pre-stored feature-content mapping model, and outputting a collagen content value. According to the invention, adaptive sampling and dynamic process tracking are realized, and the accuracy and reliability of detection are improved.

The invention provides self-repairing TPU (thermoplastic polyurethane) optical resin as well as a preparation method and application thereof. According to the self-repairing TPU optical resin disclosed by the invention, dithio diethylene glycol is deliberately selected as a cross-linking agent to introduce a dynamic disulfide bond, so that a material network is endowed with dynamic reversibility; meanwhile, a thiocarbamate bond and a dynamic metal coordination bond are introduced to a polyurethane main chain, the multi-dynamic bond action mechanism breaks through the bottleneck of low self-repairing efficiency of a single dynamic bond in the past, and on the basis of ensuring the mechanical strength performance under the normal temperature condition, the material can be effectively repaired when being subjected to microscopic damage, so that the self-repairing efficiency of the material is greatly improved. And the exchange reaction of covalent hydrogen bonds and disulfide bonds can be triggered through external stimulation, so that the self-repairing of the damaged part is realized, the anti-scraping performance of the optical element is remarkably improved, and the service life is prolonged. The TPU optical resin provided by the invention has high-efficiency self-repairing performance, is recycled and regenerated, and realizes performance balance among high refractive index, low dispersion and mechanical strength.

The application relates to the technical field of optical detection, and discloses a pigskin collagen content detection method. Before contacting a detection medium, the initial optical profile of a pigskin sample is established. According to the profile, a special detection path for the sample is generated, and the moving track and the stay node of the probe sampling are specified. The medium is injected at the starting point of the path, and a synchronization mechanism is started to synchronize the probe movement with the medium diffusion front. When the probe reaches the terminal node, the spectral sequence of each node on the path is recorded completely, and the sequence contains the dynamic characteristic absorption information of collagen. The spectral sequence is subjected to cross-node correlation fusion to generate the fusion spectral feature map of the sample. The map is compared with a pre-stored feature-content mapping model, and the collagen content value is output. The application realizes adaptive sampling and dynamic process tracking, and improves the accuracy and reliability of detection.
