Abstract: In one embodiment, an integrated light transmission/reception optical system module includes a light receiving lens, a light source, and a light transmitting mirror. The light receiving lens receives light, concentrates the received light on a light detector disposed at a rear position, and has an optical path groove formed to be directed from a circumference to a central portion and formed to expose a front side. The light source outputs a pulse laser along the optical path groove from the circumference of the light receiving lens toward the central portion of the light receiving lens. The light transmitting mirror is disposed within the optical path groove, is located on a path of the pulse laser, and reflects in a front direction the pulse laser outputted from the light source. Other embodiments are also possible.
