Abstract: A lidar system comprises a lidar transmitter and a control circuit. The lidar transmitter fires laser pulse shots into a field of view and comprises a variable amplitude scan mirror for directing the laser pulse shots at targeted range points in the field of view (FOV). The control circuit (1) controls changes in a tilt amplitude of the variable amplitude scan mirror and (2) schedules the laser pulse shots according to a plurality of criteria, including criteria that take into account a settle time arising from controlled changes in the tilt amplitude. These controlled changes can include (1) a first tilt amplitude corresponding to a wide FOV coverage zone within the FOV and (2) a second tilt amplitude corresponding to a narrow FOV coverage zone within the FOV, wherein the second tilt amplitude is less than the first tilt amplitude.

Abstract: A lidar system that includes a laser source and transmits laser pulses produced by the laser source toward range points in a field of view via a mirror that scans through a plurality of scan angles can use (1) a laser energy model to model the available energy in the laser source over time and (2) a mirror motion model to model motion of the mirror over time. A shot list for the upcoming laser pulse shots that are modeled according to the laser energy and mirror motion models can further be controlled based on eye safety and/or camera safety models to prevent the lidar system firing too much laser energy into defined spatial areas over defined time periods and thus reduce the risk of damage to eyes and/or cameras in the field of view.

Abstract: A lidar system comprises a first lens, a second lens, and a switch. The first lens has a first field of view that receives incident light from the first field of view. The second lens has a second field of view that receives incident light from the second field of view, wherein the second field of view is encompassed by and narrower than the first field of view. The switch controls which of the first and second lenses are used for detecting returns from laser pulse shots based on where the laser pulse shots are targeted in a field of view that encompasses the first and second fields of view. The switch may comprise an optical switch or an electronic switch.

Abstract: A lidar system includes a lidar transmitter and a control circuit. The lidar transmitter can controllably fire a plurality of laser pulse shots into a field of view, and the control circuit can (1) detect a target based on a return from a laser pulse shot fired at a first shot angle, and (2) in response to the detected target, (i) schedule a pulse burst to be fired at the target, wherein the pulse burst comprises a second laser pulse shot to be fired at a second shot angle and a third laser pulse shot to be fired at a third shot angle, wherein the first shot angle is between the second and third shot angles, and (ii) control the lidar transmitter to fire the scheduled pulse burst.

Abstract: A lidar system that includes a laser source and transmits laser pulses produced by the laser source toward range points in a field of view via a mirror that scans through a plurality of scan angles can use (1) a laser energy model to model the available energy in the laser source over time and (2) a mirror motion model to model motion of the mirror over time. Time slots for transmitting the targeted laser pulses can be identified using the mirror motion model, and a schedule for these pulses can be determined using energies predicted for the pulses at these time slots according to the laser energy model. Linking the model of mirror motion with the model of laser energy provides highly precise granularity when scheduling laser pulses targeted at specific range points in the field of view.

Abstract: A lidar system that includes a laser source can be controlled to fire laser pulse shots from the laser source at a variable rate of firing those laser pulse shots. The fired laser pulse shots can include scheduled laser pulse shots that are targeted at range points in the field of view. The fired laser pulse shots can also include marker shots that bleed energy out of the laser source in order to avoid reaching a threshold for available energy in the laser source and/or regulate energy amounts for the targeted laser pulse shots. A laser energy model that models how much energy is available from the laser source for laser pulse shots over time can be used to model future available energies for the laser source and determine whether any marker shots should be fired.

Abstract: Present implementations include a LIDAR system comprised of a scanning emitter and a static receiver having a detector pixel array. According to some aspects, the present embodiments reduce the physical dimensions of the detector array while maintaining effective optical performance of the system, thereby reducing overall cost, power and size of the system. In some embodiments, this is achieved by selectively emitting and receiving light in one or more wavelength bands corresponding to one or more sets of directions in which the light is emitted and received.
