Time of Flight Imaging with Single Photon Counting
نویسنده
چکیده
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 the data acquisition rate of these systems. We would like to create a flash LIDAR system, which illuminates the whole scene and uses a lens to map each point of space illuminated to a pixel on the detector. The use of Single Photon Avalanche Photodiodes (SPADs) allows us to capture data on the single photon level, which greatly reduces the signal to noise ratio needed to acquire an accurate signal.

Neural Imaging Using Single-Photon Avalanche Diodes
Introduction: This paper analyses the ability of single-photon avalanche diodes (SPADs) for neural imaging. The current trend in the production of SPADs moves toward the minimumdark count rate (DCR) and maximum photon detection probability (PDP). Moreover, the jitter response which is the main measurement characteristic for the timing uncertainty is progressing. Methods: The neural imaging pro...
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...

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 کاملPET vs. SPECT: in the context of ongoing developments
This paper intends to compare the abilities of the two major imaging modalities in nuclear medicine imaging: Positron Emission Tomography (PET) and Single Photon Emission Computed Tomography (SPECT). The motivations are many-fold: (i) To gain a better understanding of the strengths and limitations of the two imaging modalities in the context of recent and ongoing developments in hardware ...
متن کاملRapid, Globally Contiguous, High Resolution, 3d Topographic Mapping of Planetary Moons Using a Scanning Photon-counting Lidar
Introduction: Photon-counting lidar altimeters and imagers are the most efficient possible since each range measurement requires only one detected photon as opposed to hundreds or thousands in conventional laser pulse time of flight (TOF) altimeters. The GLAS altimeter on ICESat-I, for example, has a minimum detectable signal corresponding to roughly 100 photoelectrons but can produce in excess...
متن کاملProcessing time-correlated single photon counting data to acquire range images - Vision, Image and Signal Processing, IEE Proceedings-
The processing and analysis are described of range data in a time-of-flight imaging system based on time-correlated single photon counting. The system is capable of acquiring range data accurate to 1Opm at a standoff distance in the order of lm, although this can be varied substantially. It is shown how fitting of the pulsed histogram data by a combination of a symmetric key and polynomial func...
