A time-of-flight (TOF) detector is a particle detector which can discriminate between a lighter and a heavier elementary particle of same momentum using their time of flight between two scintillators [1]. The first of the scintillators activates a clock upon being hit while the other stops the clock upon being hit.
The company 'Kent K9 Detection Services' offers a RASCO system, [3] and an evolved version is fielded by Chilport for remote air sampling, known as VODS and described as 'an approved variant of the RASCO System'. [4] Towards assessing best practice, the US Coastguard reviewed the system and wrote a brief summary report in 2006. [5]
Time of flight (ToF) is the measurement of the time taken by an object, particle or wave (be it acoustic, electromagnetic, etc.) to travel a distance through a medium. This information can then be used to measure velocity or path length, or as a way to learn about the particle or medium's properties (such as composition or flow rate).
Time of flight of a light pulse reflecting off a target. A time-of-flight camera (ToF camera), also known as time-of-flight sensor (ToF sensor), is a range imaging camera system for measuring distances between the camera and the subject for each point of the image based on time-of-flight, the round trip time of an artificial light signal, as provided by a laser or an LED.
Tickets aren’t cheap though—a one-way flight from New York to Los Angeles in June costs $6,000, and a flight from New York to London costs $8,000 (one ticket is for both a dog and its human).
Time-of-flight (TOF) PET: For modern systems with a higher time resolution (roughly 3 nanoseconds) a technique called "time-of-flight" is used to improve the overall performance. Time-of-flight PET makes use of very fast gamma-ray detectors and data processing system which can more precisely decide the difference in time between the detection ...
A couple has gone viral for accusing American Airlines staff of keeping them from their dogs after their flight was delayed. The married couple from Florida, identified by the DailyMail as 42-year ...
Time of flight - this measures the time taken for a light pulse to travel to the target and back. With the speed of light known, and an accurate measurement of the time taken, the distance can be calculated. Many pulses are fired sequentially and the average response is most commonly used.
