Abstract: The present disclosure relates to transmitter modules, vehicles, and methods associated with lidar sensors. An example transmitter module could include a light-emitter die and a plurality of light-emitter devices coupled to the light-emitter die. Each light-emitter of the plurality of light-emitter devices is configured to emit light from a respective emitter surface. The transmitter module also includes a cylindrical lens optically coupled to the plurality of light-emitter devices and arranged along an axis. The light-emitter die is disposed such that the respective emitter surfaces of the plurality of light-emitter devices form a non-zero yaw angle with respect to the axis.
