我们分析了最近提出的一种快速获取反射光谱的二维（2D）空间分布的技术，以弄清楚它区分几乎相似光谱的能力随着光源光谱线带宽的增加而下降。使用实验测量的四个同色异谱样品的反射光谱进行分析，并通过具有可变带宽的光谱线模拟系统对照明的响应。结果表明，即使在照明线带宽为20-30 nm时，同色异谱样品也是可区分的。更宽的带宽允许实现对象的同时照明，这导致2D多光谱图像的采集时间的减少，这是由于发光二极管（LED）切换的并行模式中的更快操作和更高的输出功率。
We analyze a recently proposed technique for fast acquisition of the two-dimensional (2D) spatial distribution of reflectance spectra to figure out how much its ability of distinguishing almost similar spectra declines with increase of the spectral line bandwidth of the light source. This analysis was carried out using the experimentally measured reflectance spectra of four metameric samples and simulating the system response to an illumination by spectral lines with variable bandwidth. It was shown that the metameric samples are distinguishable even when the bandwidth of illuminating lines is 20–30 nm. A wider bandwidth allows implementation of simultaneous illumination of an object that leads to a diminution of the acquisition time of 2D-multispectral images due to both faster operation in the parallel mode of Light-emitting diodes (LEDs) switching and higher output power.
