用于植物科学或农业的高光谱成像系统在电磁频谱的蓝色区域（400-500 nm）通常具有次优的信噪比。通常，造成这种效应的主要原因有两个：成像传感器的低灵敏度和照明源提供的光量低。在植物科学中，蓝色区域包含有关植物生理和健康状况的相关信息。我们报告了通过使用发射峰值为 470 nm 的高亮度发光二极管 (LED) 阵列提供的补充照明，提高了高光谱成像系统在光谱蓝色区域的灵敏度。
Hyperspectral imaging systems used in plant science or agriculture often have suboptimal signal-to-noise ratio in the blue region (400–500 nm) of the electromagnetic spectrum. Typically there are two principal reasons for this effect, the low sensitivity of the imaging sensor and the low amount of light available from the illuminating source. In plant science, the blue region contains relevant information about the physiology and the health status of a plant. We report on the improvement in sensitivity of a hyperspectral imaging system in the blue region of the spectrum by using supplemental illumination provided by an array of high brightness light emitting diodes (LEDs) with an emission peak at 470 nm.
