Strategic Study of CAE 2003, Volume 5, Issue 3, Pages 39-43
The space remote sensing and information technique have become a necessary tool to observe the different scale, different layer and continuous dynamical phenomenon of oceanic resources and environment. The marine remote sensing has more advantage than the normal investigation in the collection of marine environment parameters of several yeas, even several ten years. In the 1970s the international scientists began the real time detection of oceanic environment by means of water leaving radiance measurement from satellite. China has paid great attention and has made great progress in this field since the 1980s. This paper, first, reviews the development of marine optical remote sensing in China over the last 20 years. Secondly, the neads of this technique in national rights and interests, preventing and reducing natural calamities and management and development of marine resources are discussed. Finally, the key technique and frontiers of the application of marine optical remote sensing in the monitoring of marine environment are expounded, such as marine satellite operational monitoring system, accuracy analysis and quantitization, high frequency and long term monitor data collection, the combination application of multi sensor and key technique, etc.

Super-resolution Near-field Optical Imaging and its Industrial Development
Wu Shifa
Strategic Study of CAE 2000, Volume 2, Issue 2, Pages 10-14
The super-resolution near-field optical imaging is an advanced project in the front of high engi-neering science and is an industry that should be developed early in the 21th century in China. In this paper, the historical events and PSTM developments in China are introduced. The imaging expressions of all kinds of the super-resolution near-field optical imaging systems are derived and compared with each others. In general, only with the mode of constant separation of tip-sample may obtain the pure optical image of sample, such as the image of refractive index, reflectivity or transmisivity of sample. The evanescent wave emitted from sample surface and the probe tip smaller than the diffraction limit are the two basic conditions of super-resolution in optical imaging. The other key to obtain the super-resolution is the modulated tip with vertical vibration in the mixture field of evanescent wave and propagating wave in near-field. For the transparent sample PSTM is the best to separate the pure optical image and topography of sampe. The author has applied for two invented patents on PSTM, which will be benificial to the development of PSTM industry in China.

Optical Problems in Imaging Optical Engineering
Pan Junhua
Strategic Study of CAE 2000, Volume 2, Issue 3, Pages 32-35
In this paper the critical area using imaging optics is discussed, i. e. the ground based astronomical telescopes, observing systems from the space to the Earth and the projecting lithographic systems. According to the trend of technical progress, it is unavoidable to use reflective optical systems, and consequently as-pherical surfaces. For optical system design, the main problem is how to construct an effective reflecting system which may be optimized by the optical CAD. The need of unobscurating entrance pupil leads using off-axis reflecting system and tilted mirror system. The key problem in fabrication is to make high accuracy, large relative aperture, high-order, large asphericity/aspherical slope and section symmetric surfaces. The null method is the principal way for testing aspheric surfaces up to now. The design of compensator for highorder, off-axis aspheric mirrors is worth studying yet.

Cutting-edge technologies in optical molecular imaging have ushered in new frontiers in cancer research, clinical translation, and medical practice, as evidenced by recent advances in optical multimodality imaging, Cerenkov luminescence imaging (CLI), and optical image-guided surgeries. New abilities allow in vivo cancer imaging with sensitivity and accuracy that are unprecedented in conventional imaging approaches. The visualization of cellular and molecular behaviors and events within tumors in living subjects is improving our deeper understanding of tumors at a systems level. These advances are being rapidly used to acquire tumor-to-tumor molecular heterogeneity, both dynamically and quantitatively, as well as to achieve more effective therapeutic interventions with the assistance of real-time imaging. In the era of molecular imaging, optical technologies hold great promise to facilitate the development of highly sensitive cancer diagnoses as well as personalized patient treatment—one of the ultimate goals of precision medicine.

Strategic Study of CAE 2006, Volume 8, Issue 11, Pages 74-79
Transmitting effects of aero-optics is very important to optical imaging probing system of interceptor, as it may cause displacement, jitter and blurring of image to receive for the system. The optic transmitting characteristics is analyzed when target ray goes though turbulence flow. The engineering model for optical transmitting characteristics of flow is built up and empirical model for optical imaging system induced by aero-optic transmitting effects is described. The displacement, jitter and blurring are simulated. The numerical simulation results suggest that transmitting effect of aero-optics has powerful influence on the imaging probing system, which is related to flight parameters, imaging system parameters and integration periods of imaging probing system, etc.

Recent Advances in Physical Optics Research
Huang Zhixun
Strategic Study of CAE 2006, Volume 8, Issue 2, Pages 18-29
This paper focuses on a series of theoretical and experimental studies of the physical optics, such as the Goos-Hänchen shift, the FTIR phenomena, the negative refraction index, the superluminal experiments of THz rays, and the measurement of photon rest mass. It indicates that the evanescent waves phenomena are becoming more important in physical optics research recently. For example, superluminal propagation is a result of the evanescent waves, i. e. the evanescent fields. The possibility of a finite photon rest mass remains one of the most important issues in physical optics, as it has a bearing on a series of fundamental questions. A discussion on the present situation in this area is given. Finally, the history and advances of optical frequency standard and optical frequency measurements are given in the article.

Strategic Study of CAE 2000, Volume 2, Issue 6, Pages 27-32
The principle of binary optics used for beam shaping is introduced. On the basis of the analysis of GS and YG algorithms, three algorithms are developed for phase design of the Binary Optical Element (BOE), including Global/local united searching algorithm (GLUSA), hybrid algorithm combining Hill-climbing with Simulated Annealing and its multi-resolution algorithm. For example, the BOE obtaining uniform focused spot for Inertial Confinement Fusion (ICF) is designed by the above algorithms. The simulated results show that fine phase structure and good characters of the focused spot are realized by using the hybrid algorithm. A continuous phase plate is manufactured with a rotating hollowed-out mask. The intensity distribution of the focused spot is measured by a common CCD and multi-attenuators with which the measurement dynamic range is increased .The experimental results after data processing show that the focused spot with steep edge, low side lobe, high light efficiency and fair uniformity of the main lobe without sharp peak at the zero order is obtained.
