Under the action of a continuous heat source: i) infrared images are collected for defects of different areas and shapes, ii) the temperature of different areas of the film surface is recorded, iii) the temperature changes of different locations and the shadow area of infrared defects with time are analyzed, and iv) finally, the temperature characteristic curve and the best defect detection time limit were studied. The experimental results show that the temperature trends of the defect and complete area are the same the whole time; however, there is a synchronous temperature difference, and the infrared temperature image acquisition time is clearly in the 10-20 mins. It can be regarded as the best detection time domain of the defect. When the thermal image acquisition time is 13 mins, the infrared image edge contour is the same as the real defect contour; therefore, it is the optimal detection time point.","PeriodicalId":64126,"journal":{"name":"红外技术","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46715120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to eliminate the mosaic area resulting from the processing by the image mosaic system, a new mosaic pattern without splicing the blind area is proposed in this work. First, the advantages and disadvantages of the image stitching layout patterns with and without stitching blind areas are analyzed. Second, using the image mosaic of the images obtained from three uncooled longwave infrared cameras as an example, the design and analysis of the uncooled longwave infrared camera lens is carried out. Finally, in order to obtain a better stitched image, a corresponding treatment measure is provided for the distortion of infrared cameras.","PeriodicalId":64126,"journal":{"name":"红外技术","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45266051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the theory of flexible body kinematics, the motion simulation of the sliding guide mechanism at different motion postures, length-diameter ratios and arrangement positions of the guide pin and lens, was analyzed, which influenced the lens offset and deflection. The nested steering mechanism was simulated and analyzed to verify the feasibility and meet the practical requirements of the zoom optical system. Accordingly, the infrared continuous zoom lens sliding guide mechanism was designed and fabricated. Subsequently, the zoom process of the lens was imaged. It was demonstrated that this simulation analysis provides an effective method to enable the structural design and research of infrared zoom lens.","PeriodicalId":64126,"journal":{"name":"红外技术","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44540741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The dual discrete color sources respectively produce a foreground and background color beam passing through a collimating optical system, and then form a four-bar synthetic image on the color CCD. In the experiment, we extracts the stripe from the target image at each frequency and calculates the color difference of each pixel. Then, we use the criterion to mark the detectable pixels and define the minimum resolvable E difference (MRED) and the minimum detectable E difference (MDED) as two indexes to objectively evaluate the color resolution of the color camera.","PeriodicalId":64126,"journal":{"name":"红外技术","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45771419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The occurrence of breast cancer and mortality resulting from it ranks the highest among cancer cases in women. Hence, early detection and diagnosis of breast cancer becomes extremely important. Traditional structural imaging has some limitations in early detection of diseases, while infrared thermal imaging, as a functional imaging technology, can provide effective clues for early screening of breast cancer. This work mainly reviews the usefulness of employing infrared thermal imaging in the early detection and prognosis evaluation of breast diseases.","PeriodicalId":64126,"journal":{"name":"红外技术","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46932174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To this end, 80 samples of glycerol and butanol were scanned and analyzed by means of near-infrared spectroscopy. Furthermore, in order to improve the predictive ability of the model, five quantitative calibration methods, namely, the partial least squares method, interval partial least squares method, forward interval partial least squares method, backward interval partial least squares method, and minimum forward interval method were used to establish the near-infrared detection model for glycerol and butanol content. The models were then analyzed and compared. The results showed that the model established by means of the backward interval partial least squares method was effective, and the correlation coefficients of the single component solution of glycerol and butanol were 0.99932 (glycerol) and 0.98843 (butanol), respectively. To measure the content of glycerol and butanol in the glycerol fermentation broth, a monitoring platform for glycerol and butanol concentrations was established. The correlation coefficients were found to be 0.99074 (glycerol) and 0.99261 (butanol), respectively. The results show that the NIR rapid detection model demonstrates excellent performance with regards to accuracy and rapidity and provides a new detection method for the rapid detection of glycerol and butanol in the fermentation industry.","PeriodicalId":64126,"journal":{"name":"红外技术","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45905442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
