Abstract: In one example, a method may include receiving one or more laser scan of a scene, receiving two or more camera images of the scene, determining one or more decision regions where the camera images are different from one another, detecting edges of the decision regions where the camera images are different from one another, comparing the decision regions where the camera images are different from one another inside of the detected edges with a corresponding region in the laser scan to determine which of the camera images includes a desired region that more closely corresponds to the laser scan, and generating a corrected image including the desired region that more closely corresponds to the laser scan.

Abstract: Embodiments may include methods and systems for obtaining location information regarding an object. In one example, a laser pulse may be generated. The laser pulse may be divided into a plurality of laser pulse signals. Each of the laser pulse signals may be provided to a corresponding delay path, each delay path having a different length. An output of each delay path may be directed to the object. A plurality of reflected time-separated laser pulse signals from the object may be detected. The plurality of time-separated laser pulse signals may be combined to provide a recombined laser pulse signal. The recombined laser pulse signal may be resolved to generate object location information regarding the object.

Abstract: Methods and systems for using spectrally separated light pulses to collect more LIDAR information are presented. In one example, a laser pulse may be directed to a point on an object and a corresponding return light signal may be received. The return light signal may be wavelength separated into a plurality of spectral pulse components. Each of the spectral pulse components may be propagated down a separate fiber optic delay line each having a different length to provide a plurality of time-separated spectral pulse components. The time-separated spectral pulse components may be combined to provide a recombined spectral pulse signal. The recombined spectral pulse signal can be provided to an intensity-related measuring/detection circuitry to generate corresponding object location information and object spectral information regarding the point on the object.

Abstract: Methods and systems for using spectrally separated light pulses to collect more LIDAR information are presented. In one embodiment, a monochromatic pulse is transmitted to collect range information and a white pulse is transmitted a short time afterwards to collect spectral responsivity information or color of the target. In another embodiment, the white light pulse is used to collect both range and spectral responsivity information of the target. In another embodiment, the spectral separated laser is spatially spread in order to collect range information over more than one point at a time.

Abstract: The performance of a laser scanner is optimized in the field by automatically determining appropriate laser parameters for the scan location. A laser control system uses information such as the environmental temperature to select an appropriate range of start points for various laser parameters, such as pump temperature and laser currents. Test pulses over that range can be used to determine optimal operating parameters.

Abstract: A light detection system duplicates the dynamic range of low intensity non-cooperative targets for high intensity cooperative targets. Both dynamic ranges of return light pulses are supported at the same time. In one embodiment, two beam splitters are used to reduce the intensity of reflected light that is received from high intensity sources to levels that can be accurately ranged. Ambiguity between the two paths is resolved by using an additional detector. Alternatively, one beam splitter is used to reduce the intensity of reflected light that is received from high intensity sources to levels that can be accurately ranged. The beam splitter system increases the effective dynamic range of the detection and ranging system passively without any need to reconfigure the system.

Abstract: The performance of a laser scanner is optimized in the field by automatically determining appropriate laser parameters for the scan location. A laser control system uses information such as the environmental temperature to select an appropriate range of start points for various laser parameters, such as pump temperature and laser currents. Test pulses over that range can be used to determine optimal operating parameters. In order to also meet safety regulations, the laser control system can use information such as range and pulse timing information to fire regularly spaced pulses that do not exceed acceptable exposure limits. Alternatively, the laser can be operated at a regular speed of about 24 Hz, or can be operated in burst mode where a burst of pulses creates what appears to be a brighter scan spot, but the time delay between bursts allows time for a blink reflex.
