Time 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 کاملLong-range time-of-flight scanning sensor based on high-speed time-correlated single-photon counting.
We describe a scanning time-of-flight system which uses the time-correlated single-photon counting technique to produce three-dimensional depth images of distant, noncooperative surfaces when these targets are illuminated by a kHz to MHz repetition rate pulsed laser source. The data for the scene are acquired using a scanning optical system and an individual single-photon detector. Depth images...
متن کاملTime-to-Digital Converter card for multichannel time-resolved Single-Photon Counting applications
We present a high performance Time-to-Digital Converter (TDC) card that provides 10 ps timing resolution and 20 ps (rms) timing precision with a programmable full-scale-range from 160 ns to 10 μs. Differential Non-Linearity (DNL) is better than 1.3% LSB (rms) and Integral Non-Linearity (INL) is 5 ps rms. Thanks to the low power consumption (400 mW) and the compact size (78 mm x 28 mm x 10 mm), ...
متن کاملEnhanced 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...
