A technique is presented for the automated calculation and the imaging of the electric field around a moving animal. This technique is based on the numerical analysis of an electric field using the finite difference method. Its usefulness in practice is demonstrated by applying it to a free-moving mouse. The mouse is photographed in a 35 mm monochromatic film, and it is transformed in a digital image using a flying spot scanner (FSS). This image is used as a boundary condition for the numerical calculation of the electric field. The distributions of both equipotential lines and electric lines of force are plotted on an X-Y plotter. The intensity distribution of the electric field is presented in the luminance on a CRT display of the FSS and recorded on a film. The surface electric field of the animal body is calculated by extrapolation along the electric line of force and presented in vector patterns. It is shown quantitatively that the electric field on the animal body (e. g. nose, back, ears) changes considerably as the animal changes its posture. This method is widely applicable to the objects with any shapes including a human.
