Abstract
An optical system has a LIDAR chip that includes a switch configured to direct an outgoing LIDAR signal to one of multiple different alternate waveguides. The system also includes a redirection component configured to receive the outgoing LIDAR signal from any one of the alternate waveguides. The redirection component is also configured to redirect the received outgoing LIDAR signal such that a direction that the outgoing LIDAR signal travels away from the redirection component changes in response to changes in the alternate waveguide to which the optical switch directs the outgoing LIDAR signal.
Claims17
An optical system, comprising:
- a LIDAR chip that includes a switch configured to direct an outgoing LIDAR signal to one of multiple different alternate waveguides,
- each of the alternate waveguides terminating at a facet through which the outgoing LIDAR signals passes when directed to the alternate waveguide;
- and
- a redirection component configured to receive the outgoing LIDAR signal from any one of the alternate waveguides and configured to redirect the received outgoing LIDAR signal such that a direction that the outgoing LIDAR signal travels away from the redirection component changes in response to changes in the alternate waveguide from which the redirection component receives the outgoing LIDAR signal, and
- the facets are positioned along an arced focal point line that connects multiple different focal point of the redirection component.
