Thank you dlgoff. I still could not comprehend the statement well. For example, if I have a laser beam entering the bragg cell at 40MHz and the beam coming out of the cell have a frequency of 50MHz. Is the frequency coming out of the cell always has a fixed value? Or it will shift up and down...

I know that Bragg cell used in laser doppler vibrometer (LDV) is used to give information about the direction of the velocity of the object that we measure. I also know that Bragg cell will shift the frequency of the laser beam(modulation frequency is reduced) when the object is moving towards...
