Research Progress in FDA’s Focus Areas of Regulatory Science for Drugs and Suggestions for China

Objective To sort out the focus areas of FDA’s scientific supervision and to achieve corresponding results,so as to provide some suggestions for the scientific research and innovation of drug supervision in China.Methods In-depth research was carried out in the fields of safety evaluation tools,clinical trial innovation,new methods of product quality evaluation,information science and so on.Results and Conclusion The research foundation of drug supervision related technology in China is weak,and a systematic supervision system has not been formed.Learning from the scientific experience of drug supervision in the United States,we can promote the development of the focus areas of drug supervision in China.Besides,we should improve the standard management ability while perfecting the regulations and standards system.Lastly,we should establish a system for government and industry-university-research to realize the full-cycle supervision of drugs.

Study on Focusing of Area Array Camera by Using Frequency of Images

Focusing of an area array camera is an important step in making a high precision imaging camera. Its testing method needs special study. In this paper, a method of camera focusing is introduced. The defocusing depth of camera is calculated by using the frequency spectrum of defocused image. This method is especially suitable for the focusing of the Planar Array Camera, and avoids the complicated work of adjusting the focus plane of the planar array camera in the focusing process.
