1.The behavior of optical trace is calculated by using ray tracing method when a cone ray deflects into and propagates in a prism. The calculated result is testified by the experiment, and the parameters of the hybrid integrated optical pickup device are designed.
采用光学追踪法计算了圆锥光线入射到棱镜中的轨迹 ,并对计算结果进行了实验验证 ,实验结果与计算结果相一致 ,从而获取了拾音器的光学结构参数收藏指正
2.The idea of acoustic signal processing and echo control is to allow straightforward high-quality sound pickup and playback in applications, such as a duplex device like a speakerphone, a sound source-tracking apparatus like microphone arrays, teleconferencing systems with stereo input and output, hands-free cellular phones and home theatre with 3D sound.
声学信号处理和回声控制是想在应用中能够获得高质量的拾音和重放，这些应用包括耳麦之类的双工设备、麦克风阵列之类的声源跟踪设备、立体声输入输出的远程会议系统、不用手的蜂窝电话以及3D声音的家庭影院等。收藏指正
