Abstract
A method and a device for detecting an object using a laser are provided. A laser scanner for detecting an object using a laser includes a transmitter configured to transmit a first laser, a receiver configured to receive a second laser reflected by the target object, and a reflector including a lens configured to reflect the first laser and to irradiate the first laser to the target object and to reflect the second laser to the receiver, and a mirror having a shape of a horn.
Claims16
A laser scanner for detecting a target object using a laser beam, the laser scanner comprising:
- a transmitter configured to transmit a first laser beam;
- a receiver configured to receive a second laser beam reflected by the target object;
- and
- a reflector comprising a lens and a horn-shaped mirror configured to reflect the first laser beam and to irradiate the first laser beam to the target object and to reflect the second laser beam to the receiver,
- wherein the lens is formed along an inclined surface of an edge of the horn-shaped mirror and has a convex cylindrical cross-section whose thickness decreases from a lower part to an upper part of the lens, wherein each part of the lens has a different refractive index.
A method of detecting a target object using a laser beam, the method comprising:
- transmitting a first laser beam;
- reflecting the first laser beam using a reflector comprising a lens and a horn-shaped mirror so that the first laser is irradiated to the target object;
- reflecting a second laser beam reflected by the target object using the reflector;
- and
- receiving the second laser beam,
- wherein the lens is formed along an inclined surface of an edge of the horn-shaped mirror and has a convex cylindrical cross-section whose thickness decreases from a lower part to an upper part of the lens, wherein each part of the lens has a different refractive index.
