laser signal device的意思|示意

The device was measured with a semiconductor laser, and the optical signal received by CCD was displayed on an oscilloscope.

制备的器件用半导体激光测试，用CCD和示波器接收观察光信号。

So Mr O'Brien has been working on a ceiling-based system that tracks where a receiving device is, and then sends it a signal using several laser beams from a directional transmitter.

所以O'Brien先生一直研究一套基于天花板的系统，用于跟踪接收装置所在位置，利用来自定向传送器的几束激光向该装置发出信号。

At last, has measured the quality and efficiency of exporting light beam in the signal horizontal model laser device, and analyze the measuring result.

最后测量了单横模激光器在非稳腔下的输出光束质量，以及系统的效率，并对测量结果进行了分析。

The reconnaissance distance of vehicular laser passive reconnaissance warning device was discussed in the paper. The signal to noise ratio and sensitivity of the laser detection were analyzed.

文章针对车载式激光告警器探测距离，分别对激光告警接受机的信噪比和灵敏度进行了分析计算，为系统设计和研制提供依据。

The spectrum form of square-wave controlled laser, optical signal heterodyne detecting device and principle of electrical signal demodulation are considered with emphasis.

文中着重分析了方波控制激光器的频谱形式、光信号外差探测装置和电信号解调原理。

The principle of portable laser collimator is introduced in this paper and its laser device, PSD signal processing circuits data acquisition are analysed in detail.

本文介绍了便携式激光准直仪的工作原理，分析了激光器、PS D信号调理电路及数据采集处理系统的设计。
