Abstract: A detection apparatus may include: An emitting component (301) emits a first beam. A light splitting component (3021) changes an optical path of a return optical signal from a detection region to obtain a first return optical signal and a second return optical signal, propagates the first return optical signal to a first detection component (3022), and propagates the second return optical signal to a second detection component (3023). The first detection component (3022) detects the first return optical signal to obtain a first electrical signal. The second detection component (3023) detects the second return optical signal to obtain a second electrical signal. The first electrical signal and the second electrical signal are for determining distance information of a target.
