What makes it so effective is its unique ccd - shift mechanism. the ccd sensor rests on a movable mount, which shifts according to the amount of camera shake detected by the camera s motion detectors. shifting occurs along the x, y - axes to cancel out the effects of camera shake
Ccd移位系統中的ccd感應器位於可移動的底座上，並會因應相機的移動偵測器（ motiondetectors ）所探測到的相機震動程度進行移位。該移位過程會沿著x軸及y軸進行，以消除相機震動造成的影響。 -
We consider a neutral particle with magnetic moment antiparallel to the field. with the interaction potential energy between the magnetic moment of the particle and the magnetic field, we obtain the classical motion equation of the neutral particles in the loffe trap. in some limit conditions, by using the perturbative method, the equations may take on concise forms. of which the two equations about x and y are mathieu equations. if we properly set the parameters and have the condition a > > q > 0, we can solve the mathieu equation with the traditional wkbj method. as a new attemptation, with fourier series expansion we solve the mathieu equation and obtain the classical motion law of the neutral particles
