Abstract
Proposed is a LiDAR device including: a transmission module including a laser emitting array and a transmission optic, wherein the transmission optic includes a first optical axis and a transmission entrance pupil; a reception module including a laser detecting array and a reception optic, wherein the reception optic includes a second optical axis; a case configured to accommodate at least a portion of the transmission module and at least a portion of the reception module; and a window module configured to provide an internal space for accommodating the transmission optic and the reception optic when combined with the case.
Claims17
A LiDAR device, comprising:
- a transmission module comprising a laser emitting array and a transmission optic,
- wherein the transmission optic comprises a first optical axis and a transmission entrance pupil;
- a reception module comprising a laser detecting array and a reception optic,
- wherein the reception optic comprises a second optical axis;
- a case configured to accommodate at least a portion of the transmission module and at least a portion of the reception module;
- and
- a window module configured to provide an internal space for accommodating the transmission optic and the reception optic when combined with the case;
- wherein the window module comprises a first optical window that allows light emitted from the transmission module to exit from the internal space, and a second optical window that allows light to be received by the reception module to enter the internal space,
- wherein a first laser emitting unit included in the laser emitting array is configured to emit a first laser,
- wherein the first laser emitting unit is disposed in a central region of the laser emitting array,
- wherein the first laser emitted from the first laser emitting unit is steered in a first direction through the transmission optic and exits from the internal space through a first region of the first optical window,
- wherein a second laser emitting unit included in the laser emitting array is configured to emit a second laser,
- wherein the second laser emitting unit is disposed at an edge of the laser emitting array,
- wherein the second laser emitted from the second laser emitting unit is steered in a second direction through the transmission optic and exits from the internal space through a second region of the first optical window,
- wherein the first optical window is configured to have a firstcurvature,
- wherein the second optical window is configured to have a second curvature, and
- wherein a center of the first curvature is different from a center of the second curvature.
