Analytical models of a spectral filter that contains iodine vapor and of the noise sources associated with charge-coupled-device (CCD) detector technology are combined with a planar Doppler velocimetry (PDV) signal analysis to evaluate the measurement capabilities of PDV for quantitative aerodynamic research and production wind-tunnel testing applications. The criteria for optimizing the filter cell and calibrating the frequency scale of its transmission function are described. The measurement uncertainty limits owing to scientific-grade CCD detector performance are then evaluated, and an analysis is developed of the scattering properties of aerosols suitable for aerodynamic flow seeding. The combined results predict that single-pulse PDV measurements with velocity measurement uncertainties as small as 2 m/s should be possible in aerodynamic test facilities for measurement distances of tens of meters.
将包含碘蒸气的光谱滤波器以及与电荷耦合器件（CCD）探测器技术相关的噪声源的分析模型，与平面多普勒测速仪（PDV）信号分析相结合，以评估PDV在定量空气动力学研究和生产风洞测试应用中的测量能力。描述了优化滤波器单元及其传输函数频率刻度校准的标准。然后评估了由于科学级CCD探测器性能导致的测量不确定度极限，并对适用于空气动力学流场播种的气溶胶散射特性进行了分析。综合结果预测，在空气动力学测试设施中，对于数十米的测量距离，单脉冲PDV测量的速度测量不确定度可低至2 m/s。
