Which method is 100 times faster than Time of Flight for measuring range?

The phase shift method is recognized for its efficiency in measuring range, providing results that are significantly faster compared to the Time of Flight method. This advantage comes from how the phase shift method utilizes changes in phase of a signal reflected back from a target. By comparing the phase of the emitted and received signals, it can determine distance quickly without the need for waiting for a signal to return, as is required in Time of Flight methods.

In contrast to the Time of Flight technique, which relies on timing the travel of a signal to and from an object, the phase shift method leverages wavelength and phase differences to calculate distance. This capability enables it to measure distances rapidly, often achieving speeds that are 100 times faster, which is particularly beneficial for applications needing real-time data.

Being a high-speed measurement technique, the phase shift method is ideal for applications that require fast and accurate range measurements, such as in surveying and mapping environments. Other methods, like continuous wave, frequency modulated, or laser triangulation, while useful in their own right, do not match the speed and efficiency provided by the phase shift method in this context.
