We present two versions of a chromatic confocal matrix sensor for the snapshot acquisition of three-dimensional objects. The first version contains separate illumination and detection pinhole arrays, while the second version uses a single pinhole array in double pass. The discrete lateral measurement points defined by the illumination and detection pinhole arrays are evaluated in parallel with a hyperspectral detection module. As this approach enables the spectrometric evaluation of all lateral channels, multilayer objects can be analyzed. To increase the lateral resolution the pinhole arrays are moved by micromechanical actuators. The paper includes a quantitative evaluation of the chromatic confocal module and proof-of-principle experiments with the full sensor system.
我们展示了一种用于三维物体快照采集的彩色共焦矩阵传感器的两个版本。第一个版本包含单独的照明和检测针孔阵列，而第二个版本在双程中使用单个针孔阵列。由照明和检测针孔阵列定义的离散横向测量点通过高光谱检测模块进行并行评估。由于这种方法能够对所有横向通道进行光谱评估，因此可以分析多层物体。为了提高横向分辨率，针孔阵列由微机械致动器移动。本文包括对彩色共焦模块的定量评估以及完整传感器系统的原理验证实验。
