Abstract
A noise reduction device capable of reducing noise over a wide frequency range and a detection apparatus including the same are provided. The noise reduction device includes a splitting unit configured to split pulsed light generated in a first period into three or more pulsed light beams, a delaying unit configured to provide the three or more pulsed light beams with different delay times, and a combining unit configured to combine the three or more pulsed light beams. Among the three or more pulsed light beams, two pulsed light beams whose delay times provided by the delaying unit are closest to each other are configured such that a difference between their delay times is equal to the first period.
