Abstract
Speckle removal in a pulsed hyperspectral, fluorescence, and laser mapping imaging system is described. A system includes a coherent light source for emitting pulses of coherent light, a fiber optic bundle connected to the coherent light source, and a vibrating mechanism attached to the fiber optic bundle. The system includes and an image sensor comprising a pixel array for sensing reflected electromagnetic radiation. The system is such that at least a portion of the pulses of coherent light emitted by the coherent light source comprises one or more of a hyperspectral emission, a fluorescence emission, or a laser mapping pattern.
