Abstract
(EN)
Systems for obtaining an image of a target are provided including at least one multi-wavelength illumination module configured to illuminate a target using two or more different wavelengths, each penetrating the target at different depths; a multi-wavelength camera configured to detect the two or more different wavelengths illuminating the target on corresponding different channels and acquire corresponding images of the target based on the detected two or more different wavelengths illuminating the target; a control module configured synchronize illumination of the target by the at least one multi-wavelength illumination module and detection of the two or more different wavelengths by the camera; an analysis module configured to receive the acquired images of the target and analyze the acquired images to provide analysis results; and an image visualization module modify the acquired images based on the analysis results to provide a final improved image in real-time.
