Measurement of response function in cell behavior by laser Fourier technique

Open Access

Attached document(s)



When a laser beam is fired at a moving cell, the diffraction pattern created corresponds to a Fourier transform of the scattering density of the moving cell. A stimulus applied to the cell causes several types of reaction which can be separated as factors in the Fourier representation. Deformation of motile organelles causes change in the diffraction pattern, but its translation causes no change. This enables the response function of motile organelles to be identified, when they may be hidden by changes of position.
