Abstract
This invention involves a lighting system for a portable borescope in which the light is turned on and off at video frequencies and the duration of actuation is controlled in relation to the illumination picked up by the video imager in the distal end of the borescope insertion tube. By turning off the lamp for a significant portion of the duty cycle, a significant amount of power is saved, allowing use of the system in a battery operated borescope.
