Abstract

A high precision inspection method based on image mosaic was proposed for the final optics inspection in an Inertial Confinement Fusion(ICF).The image mosaic method contains image registration stage and image fusion stage.In the image registration stage,a registration method based on feature matching of local damaged area was used to overcome the exposure difference between the subimages and the lack of image information,and the moving information in the inspection system was used in image matching to improve the inspection precision and inspection efficiency.In the image fusion stage,the Poisson image fusion was adopted to eliminate the "stitching line" caused by an exposure difference and to implement the seamless mosaic.The images of final optics inspected by Final Optics Online Inspection(FOOI)was compared with the proposed method and Scale Invariant FeatureTransform(SIFT)method,and the results show that the proposed method is superior to SIFT method.The 4×4mosaic image shows that the inspection resolution of the FOOI device in the ICF has been improved significantly by proposed method.

Abstract

Although the spectrophotometer for bio-chemical analyzer(BCA) has been applied to the properties analysis of biological samples including blood,some factors result in reducing the spectral measurement accuracy in practice.For example,the spectral absorbances are different for the various components in sample at different absorption wavebands,especially at the larger energy attentuation waveband and non-characteristic absorption waveband,which leads to the signals of strong absorbances are very large,but for weak absorbances,the singals are very small even covered by noises.Additionally,various noises generated by electronic devices and stray-light also bring serious interference for system.To solve these drawbacks above mentioned,an optimize algorithm of automatic adjustment of linear charge coupled devices(CCD) integration time combined with time-and data division was used to realize the separate exposure for strong absorption and weak absorption spectrum,which improved the weak signals under the condition of strong signals were normal.Experiments were done by using a custom-bulit high resolution spectrophotometer for BCA based on Czerny-Turner splitting-light monochrometer and linear CCD.Experimental results demonstrated that the improved method effectively enhanced the spectral measurement accuracy,system performance and signal-to-noise ratio.In additon,the spectral range of this spectrophotometer for BCA can reache 300~800 nm,wavelength resolution less than 2 nm.
