A range of approaches exist to directly measure distance as the length of the reflected optical path from laser, to a target where it is reflected, and back to a sensor. These are commonly known by various names, including LIDAR and time of flight sensors, although there is actually overlap...
The first axis, the lens plane, and the image plane intersect such that a Scheimpflug condition is achieved. The sensor signal is processed to determine a pixel signal for one or more pixels of the light sensor by determining, from the one or more pixel signals, a particle pixel signal ...

LiDAR is an example of a direct ToF sensor. Unfortunately, direct ToF is harder to design and, therefore, does not scale well to high resolutions.Indirect ToF sensors transmit continuous, modulated light. The reflected light's phase difference is measured to calculate how far an object is. A...
摘要: This article presents a direct time-of-flight (d-ToF) pulsed light detection and ranging (LiDAR) sensor with interference suppression and a linear-mode receiver implemented using discrete components. The sensor achieves 0.3° (horizontal) rule with a good approximation.关键词:...
A swept frequency light source is commonly used for automotive time-of-flight (ToF)LiDARapplications in automotive cruise control (ACC) and automotive collision avoidance systems (ACAS) [1-2] as well as in swept source optical coherence tomography (SS-OCT) [3]. In this application note, we ...
Time-of-flight 3D imaging is an invaluable remote sensing tool, but raster speeds are currently limited by pulsed-laser scanning rates. By adapting techniques from ultrafast time-stretch imaging, a new LiDAR platform scans orders of magnitude faster than today’s commercial line-scanning pulsed-...
Cobot with Time of Flight and LiDAR Dec 1 2020 Add to myAnalog Share Smart factories of the future need a robotic workforce that can comprehend their environment and interact safely with their human colleagues. This demo will highlight how ADI's ToF technology can be deployed to enhance these...
