We present signal-generation models for chromatic confocal imaging systems with illumination and detection pinholes of finite size: a collinear model that considers neither aberrations nor diffraction effects, a geometrical model that accounts for aberrations, and a wave optical model covering both aberrations and diffraction effects. These models are aimed at describing the spectral response of multipoint sensor systems with field-dependent aberrations and vignetting effects. They are suitable for single- and double-pass systems with either diffusely or specularly reflecting surfaces under test. We show experimental results to verify our models.
一种既不考虑像差也不考虑衍射效应的共线模型、一种考虑像差的几何模型以及一种涵盖像差和衍射效应的波动光学模型。这些模型旨在描述具有场相关像差和渐晕效应的多点传感器系统的光谱响应。它们适用于具有漫反射或镜面反射被测表面的单通道和双通道系统。我们展示了实验结果以验证我们的模型。
