Near-infrared super-continuum spectrum illuminating system for active hyperspectral imaging

The invention discloses a near-infrared super-continuum spectrum illuminating system for active hyperspectral imaging. The purpose that the system for active hyperspectral imaging is wide in spectral region, high in power level and uniform in illumination is achieved. The system is composed of a first super-continuum spectrum light source, a second super-continuum spectrum light source, a beacon light source, a wide spectrum optical fiber combiner, an optical fiber end cap, a transmitting module and a modulation control module. The transmitting module is an off-axis reflector set, and the modulation control module sends two electric trigger signals to the first super-continuum spectrum light source and the second super-continuum spectrum light source, so that the first super-continuum spectrum light source and the second super-continuum spectrum light source transmit super-continuum pulse with different spectral regions, the wide spectrum optical fiber combiner combines super-continuum spectrum pulses, the optical fiber end cap transits received super-continuum spectrum pulses to the transmitting module, the transmitting module performs beam expansion and focusing on the received super-continuum spectrum and transmits the spectrum to a target, and uniform illumination is achieved. The system is wide in spectral region, high in power level and uniform in illumination.
