| Abstract: | An implementation method of photoelectric detecting circuit for laser interferometry signals is provided according to the performance of the sounder. In order to design a low-noise preamplifier circuit, it is necessary to choose an appropriate photoelectric detector and to analyze the noise performance of preamplifer. A 2-step Butterworth low pass filter is designed and the simulation in Multisim environment proves that the filter is effective. A conditioning circuit is also designed for getting pulse outpu... |
