Claim 7:
8. A photoelectric chip, which is a back-incident array photoelectric chip, wherein the chip comprises multiple light splitting monitoring units, and each of the light splitting monitoring units comprises a light-transmitting groove and a photosensitive area; the light-transmitting groove is open towards any surface of the chip and runs through an absorption layer of the chip, the photosensitive area is formed in a top layer of the chip, and one end of the photosensitive area is connected to the absorption layer of the chip; and an area of the absorption layer corresponding to the photosensitive area is a photoelectric conversion area; and
a back of the chip is used as a light-entering side, and multiple beams of incident light are emitted to the chip; one part of each beam of incident light is transmitted and split out from the light-transmitting groove of the corresponding light splitting monitoring unit, and the other part of each beam of incident light enters the photoelectric conversion area of the corresponding light splitting monitoring unit for photoelectric conversion.
