Assignee: LITUREX (GUANGZHOU) CO. LTD.
Field: Optics (Instruments)
Classification: CPC G  H | IPC G  H

Claim 8:
9. A light detection and ranging (LiDAR) device that includes a laser pulse emitting unit, wherein the laser pulse emitting unit further includes:
a laser source array;
a prism array pair;
a first cylinder lens;
a second cylinder lens; and
a microelectromechanical system (MEMS) mirror;
wherein the prism array pair is positioned between the laser source array and the first cylinder lens to reduce a pitch between laser beams from the laser source array to a predetermined value;
wherein the first cylinder lens is to focus the laser beams from the prism array pair onto the MEMS mirror, which redirects the laser beams as a linear laser beam towards a predetermined direction; and
wherein the second cylinder lens is positioned at a predetermined distance from the MEMS mirror in the predetermined direction to adjust a divergent angle of the redirected linear laser beam from the MEMS mirror.
