In the operation of an acousto-optic deflector the power driving the acoustic transducer is kept on, at a constant level, while the acoustic frequency is varied to deflect the beam to different angular positions. The acousto-optic deflector makes use of the acoustic frequency dependent diffraction angle, where a change in the angle <math>\Delta \theta_d</math> as a function of the change in frequency <math>\Delta f</math> given as,<ref>{{cite web

			: <math> (12) \ \Delta \theta_d = \frac{\lambda}{\nu}\Delta f</math>

			where <math>\lambda</math> is the optical wavelength and <math>\nu</math> is the velocity of the acoustic wave.

			AOD technology has made practical the [[Bose-Einstein condensation]] for which the 2001 [[Nobel Prize in Physics]] was awarded to [[Eric A. Cornell]], [[Wolfgang Ketterle]] and [[Carl E. Wieman]].<ref>[http://nobelprize.org/nobel_prizes/physics/laureates/2001/illpres/ The Nobel Prize in Physics 2001<!-- Bot generated title -->]</ref> Another application of acoustic-optical deflection is optical trapping of small molecules.

			AODs are essentially the same as [[acousto-optic modulator]]s (AOMs). In an AOM, only the amplitude of the sound wave is modulated (to modulate the intensity of the diffracted laser beam), whereas in an AOD, both the amplitude and frequency are adjusted, making the engineering requirements tighter for an AOD than an AOM.

Hi there. Let me begin by introducing the author, her title is Sophia Boon but she by no means really liked that title. What I adore doing is soccer but I don't have the time recently. Her family members life in Alaska but her spouse desires them to move. Distributing production is how he makes a living.<br><br>Review my blog - real psychic ([http://bigpolis.com/blogs/post/6503 Related Site])
