Light output device and three-dimensional sensing device including same

A light output device comprising:

• a plurality of light source arrays disposed sequentially in a first direction perpendicular to an optical axis direction;
• a collimation lens disposed above the plurality of light source arrays;
• and
• a diffusion member disposed above the collimation lens,
• wherein each light source array includes a plurality of channels disposed sequentially in a second direction perpendicular to the optical axis direction and the first direction,
• the each light source array is set to be operated independently, and
• each of the plurality of channels included in the each light source array is set to be operated independently.

A three-dimensional sensing device comprising:

• a light emitting unit that generates an output light signal and irradiates a target region with the output light signal;
• a light receiving unit that receives an input light signal reflected from the target region;
• an information generating unit that generates information on the target region using the input light signal input to the light receiving unit;
• and
• a control unit that controls the light emitting unit, the light receiving unit, and the information generating unit,
• wherein the light emitting unit includes:
• a plurality of light source arrays disposed sequentially in a first direction perpendicular to an optical axis direction;
• a collimation lens disposed above the plurality of light source arrays;
• and
• a diffusion member disposed above the collimation lens,
• wherein each light source array includes a plurality of channels disposed sequentially in a second direction perpendicular to the optical axis direction and the first direction,
• the each light source array is set to be operated independently, and
• each of the plurality of channels included in the each light source array is set to be operated independently.
