Description: 针对非固定的电动机转速测量问题进行探讨。电动机采用在轴端或轴面粘贴反光纸的方法，每转一周可产生一个脉冲，我们将检测每个脉冲的周期通过微处理器倍频后变成占空比为50％的标准方波信号，这样不仅大大提高了脉冲信号的稳定性，而且其检测精度可由倍频器的倍频倍数来决定。而本文主要是对脉冲信号的倍频精度与稳定度进行控制.-For non-fixed motor speed measurement to explore the issue. Motor used in the shaft end or axial paste method of reflective paper, each week to produce a pulse, we will detect each pulse cycle, through the microprocessor after the octave into a 50 duty cycle for the standard square-wave signal not only greatly improve the stability of the pulse signal, and the detection accuracy by multiplier multiplier multiplier to decide. And this paper is the octave pulse signal precision and stability control. Platform: |

Description: Ultrasound Speckle Reduction Using Coded Excitation and Pulse Compression
Ultrasound images are riddled with system dependent imperfections called speckle (multiplicative noise). In ultrasonic imaging, detection of small lesions could be difficult because the effects of speckle may mask the visibility of these small targets. Therefore, the purpose of this project is to decrease speckle while maintaining some of the key salient features in the image. Images of tissue-mimicking phantoms will be created using Field II [1-2] in MATLAB (Natick, MA). Image quality metrics such as speckle signal-to-noise ratio (sSNR) [3] and contrast-to-noise ratio (CNR) [4] will be used to quantify improvements in image quality after various despeckling filters have been applied.
