For example, the light 490 emitted from the light emitting unit 421 may be transmitted to the external object 400 through the phase delay member 410. Light 490 transmitted to the external object 400 through the phase retardation member 410 is reflected from the external object 400 and transmitted to the second polarizer 440 through the phase retardation member 410. It can be. While the light 490 emitted from the light emitting unit 421 passes through the phase delay member 410, the polarization direction may change through the phase delay member 410. The light 490 reflected from the external object 400 and transmitted to the second polarizer 440 through the phase delay member 410 is in a second polarization direction 402 perpendicular to the first polarization direction 401. ) can have. The second polarizer 440 may transmit light 490 having the second polarization direction 402. The second polarizer 440 may block light 490 having the first polarization direction 401 perpendicular to the second polarization direction 402. As the second polarizer 440 passes the light 490 changed to have the second polarization direction 402 through the phase retardation member 410, the light receiving unit 422 detects the phase retardation member 410.

At least some of the light 490 emitted from the light emitting unit 421 and passing through the first polarizer 430 may be transmitted to the first reflective surface 460a of the shielding structure 460. The light transmitted to the first reflection surface 460a may have a first polarization direction 401 due to the first polarizing plate 430. At least some of the light 490 transmitted to the first reflective surface 460a may be reflected by the first reflective surface 460a and transmitted to the second polarizing plate 440. Since the second polarizer 440 passes the light 490 having the second polarization direction 402 perpendicular to the first polarization direction 401, it is reflected from the first reflection surface 460a and is transmitted to the second polarization direction 401. Light 490 transmitted to the polarizer 440 may be blocked from being transmitted to the light receiving unit 422. Since the optical axis of the second polarizer 440 is perpendicular to the optical axis of the first polarizer 430, the second polarizer 440 is configured to block the light 490 passed by the first polarizer 430. It can be.
