Title:
OPTICAL DEVICE HAVING MONOLITHIC ARCHITECTURE AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2022/119170
Kind Code:
A1
Abstract:
An optical device is disclosed. The optical device may comprise: a first substrate; a second substrate disposed on the first substrate; a light transmitting unit including a light source disposed on the first substrate and a light generating module disposed on the second substrate to be coaxially aligned with the light source; a light receiving unit including a light guide module disposed on the second substrate and a light sensing module disposed on the first substrate to be coaxially aligned with the light guide module; and a control unit, wherein the light generating module generates a light pattern emitted to the outside of the optical device by the light from the light source, the light guide module has a light transmitting layer having a predetermined pattern and passes the light, which is reflected from the outside of the optical device, to the light sensing module by the light pattern through the light transmitting layer, the light sensing module generates a first optical image by sensing the light having passed through the light guide module, and the control unit generates a second optical image by reconfiguring the first optical image on the basis of the predetermined pattern.
