説明
<jats:p>This letter reports a method for displacement measurement of the depth migration of transparent cells. This proposed optical spatial filtering method allows visualization of the transparent cells and determination of depth migration as a horizontal displacement positive or negative first order diffracted light on the detector surface. When the sample is displaced upward or downward from the focal plane, first and negative first order diffracted light form images at a different point as a light circle. The coordinates of these two light circles on the detector surface change places when the displacement of depth migration moves to the opposite direction.</jats:p>
