Modulation Frequency

Definition: Modulation frequency is the frequency (f) at which the amplitude of light is changed or modulated, in a source in frequency domain hardware.In the context of imaging biological tissue, time delays are on the order of nanoseconds (for source-detector separations of 2-3 centimeters), which yields optimum modulation frequencies in the order of 100 MHz.

Alternative definition:

Synonym: Angular modulation frequency
