MULTI-SPECTRAL LIGHTING DEVICE AND IMAGING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a new multi-spectral lighting device.SOLUTION: A multi-spectral lighting device 10 includes: a light source array including a plurality of light sources 11 arranged in a first direction; an optical filter 12 opposed to the light source array, the filter selectively transmitting a light of a specific wavelength band and having a transmission wavelength band changing in the first direction in each of the positions opposed to the plurality of light sources; and a control circuit 13 controlling the light emission intensity of each light source.SELECTED DRAWING: Figure 1A
