工作室简介：
（1）工作室成立背景历程；
自上世纪中叶信息论诞生以来，从信息论的视角理解、研究、优化光学成像系统是光学成像领域中的一个重要研究方向。由于传统光学成像系统大都是以物面到像面“点到点”的映射模式进行图像信息的采集，缺乏对图像信息的编解码功能，这使得基于信息论的传统光学成像研究更多的具有理论上的意义，对实际应用系统的优化设计更多的是起到锦上添花的作用，难以在成像功能上有实质性的突破。近年来，随着现代光场调控技术和基于光场高阶关联的新概念鬼成像技术的突破性进展，目前已经能够在鬼成像过程中利用可控的光场时空涨落对目标图像进行编码，结合现代数字光电探测技术，鬼成像实现了传统光学成像技术中所缺乏的图像信息调制-解调功能，这对从信息论的角度理解和优化鬼成像系统提出了迫切的需求和挑战。另一方面，在若干复杂环境场景中，传统成像模式所需要的“点到点”图像信息映射条件由于散射介质或障碍物的存在而无法被满足，此时无法直接对目标场景成像。以信息论的视角来理解，此时的光学传输信道受到了严重的干扰，因此，如何在这种复杂信道条件下通过设计系统以提取出目标图像信息，也是从信息论角度分析和优化光学成像所要解决的重要问题。
围绕信息光学成像这一核心研究方向，工作室前期在鬼成像系统光场信息压缩感知模式优化、透过复杂信道成像（透过散射介质成像、非视域成像等）、X光衍射鬼成像信息处理等方面开展了一系列的研究。在此基础上，将分别从信息光学成像系统的信源编码优化、复杂信道分析及射线显微应用的角度开展后续工作，促进信息论与光学成像的进一步交叉融合。

Background and History
Since the birth of information theory at the middle of last century, to understand, study and optimize optical imaging systems from the viewpoint of information theory has been an important research field of optical imaging. Due to that traditional optical imaging systems acquire image information through the “fixed point-to-point” mapping mode from the object plane to the image plane, which is lacking in "Codec" process of image information, related studies based on information theory are more meaningful in the theoretical sense, while acting as icing on the cake for optimization and design of practical systems so that substantive breakthroughs in new imaging capabilities are difficult to be made. With breakthroughs in modern light-field modulation techniques as well as new-concept ghost imaging techniques in recent years, currently it is able to encode the target image with controllable spatiotemporal fluctuations of light fields during practical ghost imaging process. Combining with modern digital photoelectric detection technologies, ghost imaging systems behave more in line with the modulation-demodulation information-transmission mode than traditional optical imaging. On the other hand, in several scenarios with complex environment condition, the "point-to-point" mapping condition required by traditional imaging can not be satisfied due to the existence of scattering media or barriers, thus it is unable to direct image the target. From the viewpoint of information theory, the transmission channel is strongly disturbed. Hence, how to design the system to extract image information under the complex channel is also an important issue to be addressed by analyzing and optimizing optical imaging systems based on information theory.
Surrounding the core research direction, information optical imaging, the lab has performed a series of studies on optimization of the compressed sensing mode of light-field information in ghost imaging system, imaging through complex channel (imaging through scattering media, non-line-of-sight imaging, etc.) and X-ray diffraction ghost imaging information processing. On these bases, subsequent research will be performed from perspectives including source coding optimization, complex channel analysis and radiographic microscopy applications of information optical imaging systems, boosting the interdisciplinary integration between information theory and optical imaging.
Main hardware equipments in the lab
* Ti: sapphire femtosecond laser system. It can be used to perform theoretical and experimental study on optical scattering in imaging through scattering media, as well as microscopic imaging experimental study in biomedical field.
* High brightness X-ray source. It can be used to perform nanoscale microscopic analysis experiment in fields of biomedicine, nano material, integrated circuit, etc.
Main research directions
(a) Optimization theory and related experimental study for information optical imaging systems.
By combining with the characteristics that the ghost imaging system based on high-order light-field correlation is able to perform "Codec" of image information, information theory will be used to study, analyze and optimize (or design) the system, including studying the information-theoretic description model of imaging systems, analyzing imaging capability and its limit, optimizing encoding light fields based on information theory, and developing information-theoretic theory and method for designing imaging system according to specific tasks.
(b) Theory and technique study for imaging through complex optical information channel
From the viewpoint of information optical imaging, study on optical scattering theory will be performed through optical channel analysis, mainly focusing on the imaging model of light field passing through scatterer or barriers. Specific studies include the theoretical model of scattering media under scaling and coherence evolution of scattered light fields, as well as study of technical methods for imaging through scattering media and non-line-of-sight imaging by combining physical model and prior information.
(c)Research on X-ray computational microscopy and precision measurement
Combining the information optical imaging theory with X-ray computational imaging techniques, researches on key technologies of X-ray nano-imaging and three-dimensional measurement will be performed. Based on the experimental platform for X-ray computational microscopy and precision measurement with high resolution, application studies in fields of biomedicine, nano material and integrated circuit will be carried out.
