Abstract

A photoelectric detection circuit and a photoelectric detector are provided. The photoelectric detection circuit includes a first photoelectric sensing element and a second photoelectric sensing element, and an electrical characteristic of the first photoelectric sensing element is substantially identical to an electrical characteristic of the second photoelectric sensing element; the first photoelectric sensing element outputs a first sensed electrical signal, and the second photoelectric sensing element outputs a second sensed electrical signal; a polarity of the first sensed electrical signal is opposite to a polarity of the second sensed electrical signal, and an amplitude value of the first sensed electrical signal is substantially identical to an amplitude value of the second sensed electrical signal.
