Abstract: A method for detecting a fault condition in a light detection and ranging transmitter includes generating a control signal that comprises an address and desired drive voltage and current information for a laser in a laser array. A drive signal is generated for the laser in the laser array in response to the generated control signal and applied to a contact associated with that address of the laser array, thereby energizing the laser at a desired output power for a desired time. A determination is made on whether the drive signal has a parameter with a value that is outside a threshold range for eye safety. The address and the fault condition is stored if the parameter has the value outside the threshold range for eye safety and reported to a host that takes an action on the LiDAR transmitter in response to the fault condition.

Abstract: The invention relates to a method of determining 3D information of a target (1000), comprising the steps of emitting, at a start time (TO), a light pulse (200) and detecting a first incident photon by one of said detector elements (32). In further steps, the time of incidence (T1) of the detection of said first incident photon is determined and at said time of incidence (T1), a time window (TW) is opened that has a predetermined duration of time (ΔΤ). In a step, all the photons detected in the window (TW) are associated with the time of incidence (T1) of the detection of said first incident photon. In further steps the cycle is repeated and further first incident photons open again a time window (TW) and so that to each of the individual detector elements (32) that detect further incident photons in the time windows (TW), other time of incidences (TT, T1V) are associated. In further steps, the time difference between the time T1 of the received photons and the time TO of the emitted pulse is determined and new cycles of detecting first incident photons and the opening of a new time window (TW) are repeated and 3D information of the target (1000) is provided. The invention is also achieved by a 3D imager (1) to provide 3D information on a target (1000).

Abstract: Provided are methods, systems, and computer program products for a LiDAR with an increased dynamic range. The method includes filtering output pulses of an SiPM device to a substantially symmetric pulse shape and capturing timing information and intensity information of the filtered output pulses for at least one predetermined intensity level;. The method includes monitoring saturation of the SiPM device, wherein a width of a saturation plateau of a respective output pulse is determined in response to saturation of the SiPM device. The method also includes extrapolating additional timing information and additional intensity information of the respective output pulse using the captured timing information, the captured intensity information, and the determined width of the saturation plateau.
