Variable beam spacing, timing, and power for vehicle sensors
First Claim
1. A system comprising:
- a plurality of light-emitter devices, wherein each light-emitter device is coupled to a respective die attach location and has a respective elevation angle, wherein the plurality of light-emitter devices is configured to emit light into an environment along the plurality of elevation angles toward respective target locations, and wherein a set of angle differences between elevation angles of adjacent light-emitter devices comprises at least two different angle difference values;
a plurality of pulser circuits, wherein the plurality of pulser circuits includes a respective pulser circuit for each light-emitter device in the plurality of light-emitter devices; and
a controller configured to control, for each given light-emitter device in the plurality of light-emitter devices, the respective pulser circuit for the given light-emitter device based on at least one of;
a determined elevation angle of light pulses emitted from the given light-emitter device or an anticipated target range of light pulses emitted from the given light-emitter device.

Abstract
The present disclosure relates to systems and methods that facilitate light detection and ranging operations. An example transmit block includes at least one substrate with a plurality of angled facets. The plurality of angled facets provides a corresponding plurality of elevation angles. A set of angle differences between adjacent elevation angles includes at least two different angle difference values. A plurality of light-emitter devices is configured to emit light into an environment along the plurality of elevation angles toward respective target locations so as to provide a desired resolution and/or a respective elevation angle. The present disclosure also relates to adjusting shot power and a shot schedule based on the desired resolution and/or a respective elevation angle.
