摘要： An apparatus includes a time-of-flight (TOF) sensor system that has an illuminator operable to emit pulses of light toward an object outside the apparatus.The illuminator is operable in a first mode in which the illuminator emits pulses having a first width and a second mode in which the illuminator emits pulses having a second width longer than the first width. The TOF sensor system further includes a photodetector operable to detect light produced by the illuminator and reflected by the object back toward the apparatus. An electronic control device is operable to control emission of light by the illuminator and is operable to estimate a distance to the object based on a time elapsed between an emission of one or more of the pulses by the illuminator and detection of the reflected light by the photodetector.

摘要： An optical distance measuring system (100) includes a transmitter (102) and a receiver (110). The transmitter (102) is configured to generate a first optical waveform (152) and direct the first optical waveform (152) toward a first scan point within a field of view (FOV) (106). The receiver (110) is configured to receive the first optical waveform reflected off a first object (162) within the FOV (106), direct the first optical waveform reflected off the first object (162) to a first photodiode group of an array of photodiode elements, and determine a distance to the first object based on a time of flight of the first optical waveform (152) from the transmitter (102) to the first object and back to the receiver (110).

摘要： A system and method for determining vehicle position uses light based communication signals and a time-of-flight (TOF) pulse. Each vehicle includes a LBC system having light emitting diodes and receiver photodiodes capable of sending and receiving pulsed light binary messages. The LBC system may also include a TOF transceiver for sending and receiving TOF pulses, or the transmitter and receiver diodes may be used to send and receive TOF pulses. Each LBC system has a controller coupled to the transmitter diodes and receiver diodes (and the TOF transceiver when present). The controller includes a processor configured to determine the distance between vehicles. Optical characteristics are used to discern relative angle, a header is used to determine relative orientation, and the time-of-flight is used to determine distance, which together may be used by the processor to determine the relative location between transmitting vehicle and the receiving vehicle.

摘要： A system and method can be provided for introducing a varying time delay between a sequence of electrical pulses in a laser range finding system. A laser beam can be modulated with the sequence of electrical pulses. The laser beam can be transmitted towards a target and a photosensitive element can receive the modulated laser beam after reflection by the target. Control circuitry can determine a distance between the laser range finding system and the target based on the varying time delay, such as to provide a reduced error in the distance determination.

摘要： Methods, systems, computer-readable media, and apparatuses for outputting light are presented. A method includes outputting, via a propagation wave source and toward a field of view (FOV), at least one propagated wave at a first power, receiving, via a sensor, a reflection of the at least one propagated wave at the first power reflected off one or more objects within the FOV, classifying, via a processor, one or more areas within the FOV into safe areas and unsafe areas based at least in part on the received reflection of the propagated wave at the first power, wherein the safe areas are deemed to be safe to receive at least one propagated wave at a second power, and outputting, via the propagation wave source and toward the safe area, the at least one propagated wave at the second power. The first power may be a lower power than the second power.
