title: [Developments in ionography (author's transl)].
abstract: Common aspects and differences of xeroradiography and ionography are reviewed briefly. Tendencies connected with latent image formation in ionography, and the development of electrostatic latent images are set out. Apart from gaseous absorbers, liquid or solid absorbers may be employed for latent image formation. A sensitivity increase in gaseous inography may be achieved by charge amplification, although with reduced resolution. As an alternative to aerosol and liquid development methods based on the distortion of deformable layers are described. A procedure yielding multiple copies with different image characteristics (edge contrast) via copies of the latent image is outlined. Finally possible closed ionography systems are mentioned which are necessary for real time imaging.
