Abstract:
The present embodiment comprises: a housing having an inner space formed therein and disposed below a windshield; an imaging device which is accommodated in the inner space and emits first linearly polarized light in a first direction; an inner mirror which is disposed apart from the imaging device in the inner space and reflects the first linearly polarized light emitted from the imaging device in the first direction; a polarization film which transmits through the first linearly polarized light reflected from the inner mirror and reflects second linearly polarized light in a second direction orthogonal to the first direction; and a phase delay mirror which is disposed outside the inner space and phase-converts, into the second linearly polarized light, the first linearly polarized light that has transmitted through the polarization film after being reflected from the inner mirror, and emits same to the polarization film, wherein the second linearly polarized light emitted from the phase delay mirror is reflected to the windshield by the polarization film, and the first linearly polarized light reflected from the inner mirror transmits through the polarization film and then proceeds to the windshield.
