In part one (chapter 2-3), two new methods and systems of optical parallel logic operation are studied. Triple-in Double-out shadow-casting logic operation system is proposed and realized for the first time. Based on this, optical full adder and 3-bit decoder array logic have been obtained. It is the first time to use coding pattern and different reading-writing model to realize BSO-PROM optical parallel logic operation where the time-order operation is avoided, so that the computing speed of optical parallel logic gate which uses this kind of spatial light modulator is increased, and it is successfully used in optical symbolic substitution .

The small hole of the optical inducer of the traditional second-generation optical mouse used for receiving the images faces downwards, and corresponding light sources (including photoelectric diode and laser diode), optic lens and photosensitive holes are arranged at the lower part of the mouse; therefore, moving the whole mouse is a relatively convenient method for generating displacement of the mouse pointer; oppositely, the small hole of the optical inducer used for receiving the images faces upwards and corresponding light sources, optical lens and photosensitive holes (7) are arranged at the upper part of the mouse; matters on the upper surface of the photosensitive hole (7) can be moved so as to lead the mouse pointer to generate the displacement, while the moving signal transmitted by a photoelectric conversion device must be reset so as to comply with the integrated mouse of the invention.

传统的第二代光电鼠标的光学感应器接收图象的小孔是向下的，对应的光源(包括光电二极管，激光二极管)、光学透镜和感光孔都是在鼠标下部分，这样要想鼠标指针产生位移较方便的方法就是移动整个鼠标；相反，光学感应器接受图象的小孔向上，对应的光源、光学透镜和感光孔(7)在鼠标上部分，要使鼠标指针产生位移就只需移动附在感光孔(7)上面的物质，但必须重新设置光电转换装置传出的移动信号，以符合本发明。

The results of Raman, SEM and EPMA tests show that the microstructure defects of the chalcogenide glasses play an important part in their second-order nonlinear optical properties. The glasses show large SNOP because of Sb2S3 microcrystal or the mental antimony in the glasses even before they were polarized. After the electrical/thermal polarized, GeSbS glasses show larger SNOP with the increase and growth of the microcrystal. The glasses show larger SNOP because of the existence of Sb2S3 microcrystal or the mental antimony in the glasses.

The first is termed aero-optic and involved optical transmission through aberrating fluid layer whose thickness, L, is smaller than or comparable with the viewing aperture dimension, A, and the turbulence scales, A , are smaller than or the order as the layers thickness:The second category, atmospheric propagation, involved optical transmission through the aberrating medium over very long propagation distance compare with the viewing aperture size, and the turbulent scales of note are generally less than or the same order as the propagation distance:Depending on the atmospheric conditions, for ground-based observatories, wave-front sensor operating at 300HZ can adequately resolved both the important spatial scales and the temporal evolution of the atmospheric-turbulence-induced aberrating wave front over viewing aperture associated with relatively large telescope.

By adjusting the positions and angles of the two DVD optical pick-up heads, the relative distance of the two laser spots can be equivalent to one quarter of the grating pitch. When the grating moves, the surface profile of the grating can be measure directly, in order to obtain the two quadrature sinusoidal signals. Then by counting the zero crossing of these two quadrature sinusoidal signals and calculating the interpolation value of these two quadrature sinusoidal signals, the moving direction and moving displacement value of the grating can be obtained.

The design principle of the laser receiver with wide FOV for the laser command guidance and laser-beam riding guidance is introduced. A mathematic model of receiving light field is presented. The formula for the viewing angle of the detecting optical system was derived according to the diffraction light field of the oblique incidence parallel light. Taking a detecting optical system with the collecting objective for example, the design characteristic that the receiving optical system needs not only an extra large relative aperture but also an unvignetting receiving performance is discussed on the premise of meeting the requirement of 1064nm WFOV laser receiver.
