In this paper, three autofocusing evaluation functions, variance, Fourier spectrum and standard deviation correlation, are analyzed and demonstrated based on experimental investigation. By using an US Air Force test target as the microscopic object, the three autofocusing evaluation functions are compared and analyzed based on Fresnel and angular spectrum algorithms, including unimodality, sharpness, veracity, distance range and computing time. The results show that there are better unimodality near the focused image plane for all the three autofocusing evaluation functions, and the same focused position is obtained by these algorithms. Fourier spectrum algorithm is the optimal one in digital holographic microscopy because of its most time-efficiency. Fresnel transform algorithm can be absolutely used to digital holographic autofocusing. Moreover, the focusing computation time can be decreased dramatically by choosing part of the reconstructed image as the focusing evaluation area. method, which is done in the reconstruction process only by computer procedure. The key of the digital holographic autofocusing is focusing evaluation function. Recent year, many focusing evaluation functions have been proposed (8-11), but most of them are applied to the on-axis digital holography. The studies of the evaluation functions that can be used to off- axis Fresnel digital holography with pre-magnification based on the Fresnel transform algorithm have not been reported up to now. In this paper the performance of the three functions are testified and compared experimentally firstly. Then the focusing evaluation method based on the part of the entire image plane is studied.","PeriodicalId":6416,"journal":{"name":"2009 Symposium on Photonics and Optoelectronics","volume":"69 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2009-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84234475","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 single-factor method, volatiles of temperature-pressure forming materials by cotton stalk was studied by Py-GC/MS to control indoor air pollutions. Therefore, Py-GC/MS was used to analyze the components from pyrolysis products of temperature-pressure forming materials by cotton stalk,. After treated with freeze-drying, the comminuted power of temperature-pressure forming materials by cotton stalk was pyrolyzed in He atmosphere at 450�� , then the pyrolysis product was analyzed by online linked GC/MS. Relative content of each component was determined by area normalization. The main and abundant constituents were arbon dioxide, ethene, ethoxy-, 1,6-anhydro-.beta.-D-glucopyranose, phenol, 2-methoxy-4-(1-propenyl)-, cedrol, thylene oxide, butanal, ethanone, 1-phenyl-, oxime, and so on. More than 30 compounds were identified in the pyrolysis products of Cotton stalk by the Py-GC/MS analysis. Most of the pyrolysis products could be used as biomedicine. But some of the volatiles of temperature-pressure forming materials by cotton stalk was toxic. And this meant that cotton stalk need be pretreatment.","PeriodicalId":6416,"journal":{"name":"2009 Symposium on Photonics and Optoelectronics","volume":"49 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2009-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82104318","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}

Here the female adult mites were treated by the KFCE-2 extract of K. scoparia, the effective ingredient of the extract of K. scoparia. The toxicosis symptoms of T. viennensis in response to the the KFCE-2 extract of K. scoparia were observed. After treatment, the mites went through four phases: the motionless phase (0-4h), the excited phase (4-8h), the convulsion phase (8-16h) and the death phase (16-24h). The treated mites showed the typical toxicosis symptoms, for example overexcitation, body inclination, kinetic ataxy and limb twitching. Then the protein content, the protease activity, the glutathione-S-transferase (GSTs) activity, the acetylcholine esterase (AchE) activity and the monoamine oxidase activity of the mites treated with the KFCE-2 extract of Kochia Scoparia were assayed. The results showed that the protein content and the activity of protease in T. viennensis treated with the extracts of K. Scoparia were increased and the activity of protease had the negative relationship with the protein content. The activity of GSTs was induced by the KFCE-2 extract of K. Scoparia. The activities of the AchE and the monoamine oxidase of the treated mites were inhibited. The inhibiting effects of AchE and monoamine oxidase indicated that the nervus centralis system was the main target of the extract of K. scoparia. The long time inhibition of the acetylcholinesterase activity by the KFCE-2 extract of K. scoparia blocked the nerve conduction of the treated mites and caused the treated mites to die.
