Abstract 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.
