Real-time recording of light patterns in heavy hydrocarbons: a theoretical analysis.
It has been experimentally shown in recent papers that the surface profile of a thermocapillary liquid submitted to heating by a nonuniform light beam undergoes a time-dependent deformation. The profiles corresponding to illumination with (a) a Gaussian laser beam, (b) a point source, (c) a fringe system, and (d) a circular Gaussian speckle pattern are calculated. This study sets some theoretical bases for practical utilization of highly viscous liquid films as transient photographic receivers.
