dToF(direct Time-of-Flight),即直接测量飞行时间。dToF核心组件包含VCSEL、单光子雪崩二极管SPAD和时间数字转换器TDC。SPAD是一种具有单光子探测能力的光电探测雪崩二极管,只要有微弱的光信号就能产生电流。dToF模组的VCSEL向场景中发射脉冲波,SPAD接收从目标物体反射回来的脉冲波。Time Digital Converter(TDC)能够记录...
dToF(英文名为Direct-Time of flight,中文直译为直接飞行时间),工作原理非常简单,发射设备会首先发射光脉冲,当光脉冲遇见障碍物时会发生反射,已知光的传播速度是一定的,当距离不同时,接收反射光线的时间也不同,通过记录光脉冲的反射时间,就可以计算出光脉冲发射位置到物体位置的距离,不断的重复这一过程,就能绘制出物...

The TMF8801 is a true direct time-of-flight (ToF) sensor system in a single modular package which offers highly accurate depth accuracy detection through a sub-nanosecond light pulse and an antialiasing “stop-watch” method to measure round-trip time of
ON Semiconductors has introduced a single point direct Time of Flight (dToF) light detection and ranging (LiDAR) Solution with Fast Response Time and High Detection Efficiency for Industrial Range Finding Applications.
A time of flight direct recoil and ion scattering spectrometer beam line (10). The beam line (10) includes an ion source (12) which injects ions into pulse deflection regions (14) and (16) separated by a drift space (18). A final optics stage includes an ion lens and deflection ...
Direct time-of-flight (dToF) sensors are promising for next-generation on-device 3D sensing. However, limited by manufacturing capabilities in a compact module, the dToF data has low spatial resolution (e.g., ~20x30 for iPhone dToF), and it requires a super-resolution step before being ...

To this end, a unique time-of-flight (TOF) spectrometer, which constitutes the backbone of a new method to study liquid surfaces, was constructed and commissioned. The performance of the spectrometer is demonstrated in a number of exemplary TOF spectra obtained from liquid glycerol. Moving from ...
Time of Flight Mass Spectrometry (ToF-MS) is defined as a technique that measures the time taken by ions of different masses to travel a fixed distance after laser ionization, based on their mass-to-charge ratio. AI generated definition based on: Analytica Chimica Acta, 2010 ...
