Enhanced single-photon time-of-flight 3D ranging.
We developed a system for acquiring 3D depth-resolved maps by measuring the Time-of-Flight (TOF) of single photons. It is based on a CMOS 32 × 32 array of Single-Photon Avalanche Diodes (SPADs) and 350 ps resolution Time-to-Digital Converters (TDCs) into each pixel, able to provide photon-counting or photon-timing frames every 10 µs. We show how such a system can be used to scan large scenes in...
متن کاملTime-of-Flight Optical Ranging System Based on Time-Correlated Single-Photon Counting.
The design and implementation of a prototype time-of-flight optical ranging system based on the time-correlated single-photon-counting technique are described. The sensor is characterized in terms of its longitudinal and transverse spatial resolution, single-point measurement time, and long-term stability. The system has been operated at stand-off distances of 0.5-5 m, has a depth repeatability...
متن کاملEnhanced performance photon-counting time-of-flight sensor.
We describe improvements to a time-of-flight sensor utilising the time-correlated single-photon counting technique employing a commercially-available silicon-based photon-counting module. By making modifications to the single-photon detection circuitry and the data analysis techniques, we experimentally demonstrate improved resolution between multiple scattering surfaces with a minimum resolvab...
متن کاملTime of Flight Imaging with Single Photon Counting
The holy grail in LIDAR technologies is a cheap, portable unit that costs less than $200 and works in full sunlight. This could be used for self-driving cars and robots, to help them map the world around them. Current LIDAR technologies, used by Google self-driving cars, and others, are scanning LIDAR units. The moving parts make these systems more apt to break, and the scanning method limits t...
متن کاملSubcentimeter depth resolution using a single-photon counting time-of-flight laser ranging system at 1550 nm wavelength.
We demonstrate subcentimeter depth profiling at a stand off distance of 330 m using a time-of-flight approach based on time-correlated single-photon counting. For the first time to our knowledge, the photon-counting time-of-flight technique was demonstrated at a wavelength of 1550 nm using a superconducting nanowire single-photon detector. The performance achieved suggests that a system using s...
