Lock-in Time-of-Flight (ToF) Cameras: A Survey [PDF]
IEEE Sensors Journal, 2011 This paper reviews the state-of-the art in the field of lock-in time-of-flight (ToF) cameras, their advantages, their limitations, the existing calibration methods, and the way they are being used, sometimes in combination with other sensors. Even though lock-in ToF cameras provide neither higher resolution nor larger ambiguity-free range compared to ...

Distance errors correction for the Time of Flight (ToF) cameras
2008 IEEE International Workshop on Imaging Systems and Techniques, 2008The Time of Flight (ToF) cameras, using their own light source, deliver two images simultaneously: brightness image and distance image and so they become 3D camera. At present, in spite of a theoretical very good resolution in distance, the distance errors are unacceptable big and not under control due to the multiple reflexions of the active light ...

Interference mitigation technique for Time-of-Flight (ToF) camera
2016 Eighth International Conference on Ubiquitous and Future Networks (ICUFN), 2016Time-of-Flight (ToF) camera has become an attractive source of applications in location-based services, autonomous navigation, object localization for robotic manipulation, ego-motion estimation, etc. Besides, these services demand centimeter level accuracy to provide the required services. Though ToF cameras can provide high accuracy in location-based

Tandem time-of-flight (TOF/TOF) mass spectrometry and the curved-field reflectron
Journal of Chromatography B, 2007The curved-field reflectron (CFR), when used as the second mass analyzer in a tandem time-of-flight mass spectrometer, provides a design that enables the use of very high energy collision-induced dissociation (CID). Specifically, this is because the wide energy bandwidth of the CFR obviates the need for floating the collision region to decelerate the ...

Time of flight (TOF) measurement of adjacent pulses
2001 IEEE Nuclear Science Symposium Conference Record (Cat. No.01CH37310), 2005Time of Flight (TOF) measurement technique of adjacent pulses with sub-nano second interval is presented. In the conventional TOF measurement, the measurement of adjacent pulses is restricted to dead time or recovery time of a single TDC circuit. In the proposed TOF measurement technique, adjacent pulses are distributed to multiple TDCs in the order of

Trotz steigender Verkehrsdichte ist die Zahl der Verkehrsunfalle mit Personenschaden in den letzten Jahren gesunken. Um zukunftige Fahrzeuge sowohl fur die Insassen als auch fur andere Verkehrsteilnehmer noch sicherer zu machen, wird eine zunehmend dreidimensionale Umfelderfassung durch das Fahrzeug notwendig.

Multi-camera interference cancellation of time-of-flight (TOF) cameras
2015 IEEE International Conference on Image Processing (ICIP), 2015In the applications based on depth, multiple TOF cameras are often required to capture the same scene. But if multiple cameras operate simultaneously on the same frequency, they interfere with each other. The multi-camera interference causes a lot of errors in depth measurement. The depth quality is severely reduced, which limits the application of TOF

Tandem time-of-flight mass spectrometer (TOF-TOF) with a quadratic-field ion mirror
Review of Scientific Instruments, 2002A tandem time-of-flight (TOF-TOF) mass spectrometer comprised of two ion mirrors is described. The first ion mirror, which is a linear-field, single-stage mirror (MS1) with an intermediate collision cell, has been designed to provide the temporal focus necessary for the second, quadratic-field ion mirror (MS2) to function effectively.

A Concise Review on Time of Flight (TOF) Mass Spectrum
Academic Journal of Research and Scientific Publishing, 2023Time of Flight Mass Spectrum is a method of mass spectrometer depending on the time which has been taking to reach the detector (usually located between 1 to 2 min from the source to separate ions) where the Sample is taken and mixed with matrix {the matrix is made up by chemical compound (2,4 Benzoic acid and cinamic acid) and they act as chemical ...
