The influence of ambient temperature on the PIDE was researched and the relationship between the PIDE and microstructure height error within a certain temperature range was analyzed. For a DOE working within an 8-12  m long-waveband infrared range, the influence of temperature on the diffraction efficiency was significant as the wavelength deviated from the designed value. The peak relative microstructure height error corresponding to the 100% diffraction efficiency changed with the change of temperature. When the relative microstructure height error of the DOE was within ±15%, the diffraction efficiency was higher than 91.89% in the temperature range from － 40 ℃ to 80 ℃ and the PIDE was higher than 88.58% in the entire","PeriodicalId":64126,"journal":{"name":"红外技术","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48810545","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 base layer is compressed by a plateau-histogram equalization algorithm. The detail layer is denoised by a median filter first, and then the potential and small target details are enhanced by nonlinear mapping. Finally, the image is integrated according to a certain weight to obtain the enhanced details. Based on the subjective and objective experimental results, compared with algorithms based on mapping, histogram equalization, and a bilateral filter, this algorithm can improve the contrast of the target scene of the infrared image in the process of dynamic range reduction.

We propose a spatial and time domain filtering combined infrared image enhancement algorithm to improve existing algorithms, suppressing image background noise from multiple directions, enhancing image detail information, strengthening damage edge contours, accurately identifying and extracting damaged parts of steel components. The processing results are quantitatively evaluated by clarity, contrast, peak signal-to-noise ratio (PSNR) and mean square error.

The aim of our design is to address the disadvantages of the complex parameters and the delay response of the trace differentiator (TD) and expansion state observer (ESO) module. The improvement simplified the TD and ESO module, and the adjustable parameters were minimized. This helps the motor to adapt to an environment with large internal and external interferences, and to achieve high precision and a rapid response. The improved ADRC was then employed in the servo pendulum scanning mechanism of an actual project, and its performance was compared to a traditional PID controller under similar conditions. The results confirm that the improved ADRC performs much better than the PID as follows: the 0°/s  10°/s response time is 75 ms, the overshoot is less than 6%, while the steady-state accuracy is within ±1%. Further, the speed fluctuation of the variable speed tracking process is small without overshoot, the scanning cycle time fluctuation is less than 0.0041 s, and the starting angle positioning accuracy is better than 0.0015°.

These defects decrease strength and cause safety concerns during use. Composite gas cylinders containing internal defects show no obvious macroscopic deformation, and thus, it is difficult to directly detect them. The current gas cylinder testing program lacks an effective means to rapidly detect internal defects in the winding layer, which may result in missed inspections of cylinders containing internal defects. This paper proposes a defect detection scheme based on a combination of the existing key problems associated with CNG composite gas cylinder testing and the existing gas cylinder testing standards and processes. The proposed defect detection scheme uses surface thermal imagery of the steam cleaning process inside the gas cylinder. The scheme uses the steam in the cylinder flushing process as the internal thermal excitation of the cylinder. Using the transient temperature distribution of the cylinder surface recorded by an infrared camera, an artificial neural network is applied to locate and quantitatively identify the defects in the cylinder winding layer. This experimental research shows that the artificial neural network can accurately locate and quantitatively identify the defects in the cylinder winding layer with high recognition efficiency, which is suitable for online detection of gas cylinders.","PeriodicalId":64126,"journal":{"name":"红外技术","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48409893","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}
