Abstract: A vehicle grille includes: a grille panel; a lens panel disposed at a rear side of the grille panel, formed in a same shape as some or entire area of the grille panel, and, when a light is incident, configured to allow some of the light to propagate in the lens panel and emit some of the light to an outside of the lens panel; and a housing disposed on a rear surface of the lens panel, formed in a same shape as the lens panel, and including a coupling provision hole configured to allow a front surface of the lens panel to be coupled to a rear surface of the grille panel at a rear side of the lens panel, wherein the rear surface of the lens panel and a front surface of the housing are coupled at the front side of the lens panel.

Abstract: A laser transmitting and receiving module for a light detection and ranging (LiDAR) may include a laser light source; a transmission optical phased array (OPA) device configured to emit laser light from the laser light source into a two-dimensional (2D) area; a reception OPA device configured to receive reflected laser light after being emitted by the transmission OPA device; a mixer configured to mix the laser light with the reflected laser light received by the reception OPA device; and a photo detector configured to detect an optical signal mixed by the mixer.
