     Based on the GTD(Geometry Theory of Diffraction) model and ideal point scatterer model of radar target in high frequency domain, the overcomplete dictionaries matching with radar measurement model and the scattering models are constructed. With the structure characteristics of the dictionaries, the FFT-based and Toeplitz matrix-based fast algorithms are presented for the formation of supper-resolution range profile.

Near-field optical scanning(NFOS) is one of the high techniques developed in recent years.There isn′t news about Ultranear-field optical scanning(UNFOS) for the present.This paper discusses the principles of UNFOS microscopy and its supper-resolution theory.

近场光学扫描技术是近年兴起的高新技术之一。超近场光学扫描尚未见报导。本文讨论超近场光学扫描显微镜的工作原理及其超分辨理论。

The threedimensional supper resolution properties of a doublet are analyzed by the scalar theory of diffraction. The numerical results from the designed doublet show that the intensity of the main disk is 57.14 times as much as that of the secondary disk, and 2.25 times as much as that of the main disk produced by only using a single lens. And the radius of the main disk is 0.49 times as much as that of a single lens. Though the intensity rate of the main disk and the secondary disk along the optical axis is...

The threedimensional supper resolution properties of a doublet are analyzed by the scalar theory of diffraction. The numerical results from the designed doublet show that the intensity of the main disk is 57.14 times as much as that of the secondary disk, and 2.25 times as much as that of the main disk produced by only using a single lens. And the radius of the main disk is 0.49 times as much as that of a single lens. Though the intensity rate of the main disk and the secondary disk along the optical axis is basically the same as that of a single lens, the depth of focus of the doublet is smaller than that of a single lens. These results indicate that the supper resolution in both transeverse and axial directions can be obtained meanwhile by the use of doublet. It is found by comparison that the 3D imaging power of the doublet is better than those of either annular or phase pupils. Therefore, the doublet can become a perfect element in the 3D imaging of confocal microscopes and in nearfield optical recording.

应用标量衍射理论分析了双胶合透镜的三维超分辨成像特性。对于所设计的双胶合透镜,数值模拟表明,焦平面上主瓣的强度是第1旁瓣的57.14倍,是单一个透镜主瓣强度的2.25倍,而主瓣的半径则是单一个透镜的0.49倍;轴线方向上,主瓣与第1旁瓣的强度之比与单一个透镜的基本相同,但是双胶合透镜的焦深则比单一个透镜的小0.25倍。说明双胶合透镜在横向和轴向同时具有较强的超分辨能力。通过与加圆环光瞳或加相位光瞳的方法比较发现,双胶合透镜具有较好的三维成像能力,可以作为共焦3 D成像和近场光学记录的理想光学器件。

Since seismic data are band-limited, it leads to singularity of extrapolation of well-log data when using seismic data. To overcome the singularity, a novel technique based on frequency-shift, which is popular in communication, is proposed in this paper to extend the bandwidth of seismic data. It transforms the band-limited seismic data into pseudo-supper-resolution data by frequency-shift to control the extrapolation of well-log data. To be seasoned with time-variable wavelet, automatic seismic event...

Since seismic data are band-limited, it leads to singularity of extrapolation of well-log data when using seismic data. To overcome the singularity, a novel technique based on frequency-shift, which is popular in communication, is proposed in this paper to extend the bandwidth of seismic data. It transforms the band-limited seismic data into pseudo-supper-resolution data by frequency-shift to control the extrapolation of well-log data. To be seasoned with time-variable wavelet, automatic seismic event tracking and time-frequency techniques are applied to extrapolate well-log data along the stratum adaptively. The results of the extrapolation of velocity and reflectivity show a good perspect of application.
