多通道彩色共聚焦成像系统研究
Research on a multi-channel chromatic confocal imaging system
摘要
Abstract
To address the limitations of slow scanning speed and high system complexity in traditional point-scanning chromatic confocal three-dimensional imaging technology,a multi-point synchronous imaging system based on fiber array and galvanometer-based optical switching mechanism is proposed.The system employs a 32-channel one-dimensional fiber array as the detection core,combined with a high-numerical-aperture dispersive lens and a high-speed galvanometer,to achieve rapid multi-point data acquisition and high-precision topographic reconstruction.Furthermore,a peak-search algorithm is proposed to effectively enhance the accuracy of wavelength determination of the system.The calibration results demonstrate that the system has a longitudinal accuracy of 0.14 µm at 580 nm and 2.46 µm across the working spectral range of 450-700 nm.Based on this,the system has been successfully applied to the inspection of integrated circuit micro-topography.This system significantly improves measurement efficiency while maintaining high resolution,showing strong potential for industrial online applications.关键词
