Claim 12:
13. A light detection and ranging (lidar) apparatus comprising:
a light sensing system comprising:
a light source comprising an upper electrode, a lower electrode, and a slit-shaped opening, and configured to emit a linear light beam through the slit-shaped opening,
a lens that is integrated with the light source on the upper electrode of the light source on which the slit-shaped opening is formed, extends in a length direction of the slit-shaped opening, and is configured to make the linear light beam traveled in the length direction of the slit-shaped opening and emitted through an output end of the slit-shaped opening as a point light at a far-field, and
a light receiver configured to receive the point light that is emitted from the light source towards an object, focused or collimated by the lens, and reflected by the object; and

a processor configured to control the light sensing system and to analyze the point light received from the light sensing system,
wherein the lens has a half cylinder shape having two opposing flat semicircular bases, and a curve portion and a flat rectangular portion that oppose each other and are provided between the two opposing flat semicircular bases.
