Abstract

为了满足现代工业领域中对复杂结构产品的高精度多自由度测量需求,构建了多自由度联合采集系统模型。建立了宽谱段相移干涉多自由度采集系统模型,并对系统中的光学部件进行了设计;以相移干涉技术为基础,提出了多自由度联合测量算法,并分析验证了所设计系统的合理性;根据仪器的物理和光学参数对算法进行了具体实现,基于Simulink的仿真试验结果表明:深度测量精度在μm级,测量范围在m级;光谱检测分辨率在nm级,测量带宽300 nm,覆盖整个可见光区域,光谱准确度为0.2 nm,误差率小于0.1%。该系统满足了现代工业精密测量中高深度分辨率、宽深度测量范围、高光谱准确度、高光谱分辨率的要求。
