  • Study on nonlinear process of remote sensing camera Imaging at visible wavelengths
    SPIE, 2017
    Co-Authors: Zhang Xing, Liu Zhaohui(刘朝晖), Zhou Liang(周亮), Li Wenhao
    Abstract:

    As the atmospheric environments get more complex, the surface characteristics are diverse, spaceborne remote sensing cameras with the characteristics of large aperture, long focal length, and small size are demanded ever-increasing, and the high-sensitivity photoelectric detectors are required to detect more observing targets, the nonlinear process of remote sensing Imaging system is worth consideration. In this paper, time delay integrated charge-coupled device (TDICCD) is used as an example to analyze Imaging chains of space remote sensing system at visible wavelengths. The nonlinear process influenced by atmospheric radiation transmission mode, the reflection characteristics of earth surface, ground-Air couping effect, Imaging optical system, TDICCD photoelectric detector, Imaging Electronics system, data transmission/compression system, and ground station system is researched in detail. At the same time, the method to reduce the nonlinear effects of the image is discussed. In order to apply the space remote sensing information to all walks of life effectively, the nonlinear process will be improved by high-precision atmospheric radiation transmission calculation, reducing the move of the image plane and the noise of the Electronics system, designing the A/D converter with stable gain coefficient, optimizing the compression/decompression process, and reducing information loss of the remote sensing Imaging system from satellite to the ground station system. © 2017 SPIE.

  • polymersomes for drug delivery design formation and characterization
    Journal of Controlled Release, 2012
    Co-Authors: Jung Seok Lee, Jan Feijen
    Abstract:

    In the last past dozen years, polymersomes (Ps) have attracted tremendous attention as versatile carriers because of their colloidal stability, tunable membrane properties and ability in encapsulating or integrating a broad range of drugs and molecules. Relatively long blood circulation times of Ps can be accomplished when block copolymers with a poly(ethylene glycol) (PEG) are used for the formation of Ps. A number of Ps has been developed for new possibilities and applications in drug delivery, medical Imaging, Electronics and nanoreactors. In particular, Ps prepared by using biodegradable and/or stimuli-sensitive block copolymers that are responsive to various internal or external stimuli are of great interest for such applications. In this review, recent advances of Ps as drug delivery systems are discussed. Critical factors that influence the formation of Ps are also addressed. The review describes preparative methods and characterization techniques for Ps. Moreover, protein and cell interactions with Ps, in vivo circulation kinetics and biodistribution of Ps are addressed.
