ABSTRACT:
A method for producing a visible image of an object is disclosed in which a fermental plate is illuminated with ultrasonic waves and a latent image of the object is therefore produced therein which is developed using a solution of chromogenic substrates, comprising, for example, hydrogen peroxide and a water-soluble aromatic amine. An apparatus to practice the disclosed method comprises an ultrasonic generator to generate ultrasonic waves illuminating the object, a fermental plate to receive and convert the ultrasonic waves passed through the object to a visible image, and a tray filled with a developer to develop the latent image of the object in the fermental plate.
