我们设计和实验证明 布拉格光栅波分复用器 三波长的平面光波电路复用 公交车站台。1310和1550 nm的光，被设计成 由一个半周期通过定向耦合器分离后 和一个完整的周期耦合作用与0.07和0.19分贝的损失， 分别。1492 nm的光反射回来的布拉格 光栅对定向耦合器及其制作少损失 超过2分贝。我们也介绍和讨论新概念 集成光学三工收发器，使用此过滤器。 (We designed and experimentally demonstrated a Bragg grating-assisted wavelength-division-multiplexing filter for the three-wavelength multiplexing on a planar-lightwave-circuit platform. The 1310- and 1550-nm lights were designed to be separated after passing the directional coupler by a half-cycle and a full-cycle coupling actions with losses of 0.07 and 0.19 dB, respectively. The 1492-nm light was reflected back by a Bragg grating fabricated on the directional coupler and its loss was less than 2.0 dB. We also introduced and discussed the new concept of an integrated optical triplexer transceiver using this filter.)

提出了一种新的基于小波包变换 和偏斜度的检测方法。该方法利用小波包对图像进行多尺度分解，解决了高频段分辨率低的问题； 并提出了一个基于偏斜度的高斯判别准则，用于对小波包分解系数进行高斯性检验，最终得到了 小目标的精确检测(The wavelet packets were applied to decompose the image into pyramid subbands at different scales and solve the problem of the higher frequencies having lower resolutions. Then a Gaussian measurement criterion based on skewness was proposed to test the Gaussian nature of the wavelet packet coefficients and finally the exact detection result was obtained. )
