SYSTEM AND METHOD FOR SPECTRAL INTERPOLATION USING MULTIPLE ILLUMINATION SOURCES

An optical detector (110) is provided with multiple light sources (Lx) having distinct spectral characteristics, which are controlled on/off across a range of lighting intensity combinations. A measurement sensor (213) receives radiated light that is reflected from a target surface via confined optical channels, and generates representative output signals. A local controller (205) or a remote computing device (130) receives the output signals or corresponding messages from the optical detector, and generates a low resolution spectral data set based on the signals for each of the lighting intensity combinations. The low resolution spectral data set is interpolated based on machine learning algorithms trained with high resolution data from a reference device to generate a high resolution spectral data set associated with the target surface. 光学检测器（110）设置有具有不同光谱特性的多个光源（Lx），其跨照明强度组合的范围被控制开/关。测量传感器（213）接收经由受限光学通道从目标表面反射的辐射光，并生成代表性的输出信号。本地控制器（205）或远程计算设备（130）从光学检测器接收输出信号或对应的消息，并基于针对照明强度组合中的每一个的信号生成低分辨率光谱数据集合。低分辨率光谱数
