A system for calibrating the light sensitivity of a camera includes a light emitter for emitting a light pulse, a fiber splitter for receiving the light pulse via an input port and providing first and second portions of the light pulse to respective first and second output ports, and a light collector for receiving the first portion from the first output port and converting the first portion to a first signal representative of a light characteristic of the first portion. A first fiber optic cable connects the light emitter and the input port, a second fiber optic cable connects the first output port and the light collector, and a third fiber optic cable has a first cable end connected with the second output port and a second cable end for emitting the second portion of the light pulse for capture by the camera. A related method is also provided.
