Abstract
A photoelectric conversion device uses an optical coupler to divide a light beam emitted from a light emitter into two portions according to a predetermined ratio. A first light beam portion is guided to an optical fiber, and a second light beam portion is guided to a light receiver. The light receiver can detect an intensity of the second light beam portion. In this way, a processor can calculate an intensity of the light beam emitted from the light emitter accordingly.
