Stroboscopic endoscopic systems and related methods employ intermittent energization of one or more light sources to generate a sequence of light flashes. A stroboscopic endoscope system includes an endoscope, an imaging device, a light source, a light transmission assembly, and a controller. The imaging device is configured for imaging an object illuminated via the endoscope. The light transmission assembly is configured to transmit light generated by the light source to the endoscope. The stroboscopic endoscopic systems and related methods employ approaches for increasing the amount of illumination light emitted by the endoscope.
