| Abstract: | This paper studies second-order positive feedback band pass filter and points effect of the filter on measuring accuracy of laser angle meter. It provides a theoretical basis for determination of filter parameters, design of optical modulator and selection of motor in actual circuit design. Also it offers a way to effectively improve angle measuring accuracy and decrease the deviation. |
