G03
Note(s)
In this class, the following terms are used with the meaning indicated:
"records" means photographs or any other kind of latent, directly-visible or permanent storage of pictorial information, which consist of an imagewise distribution of a quantity, e.g. an electric charge pattern, recorded on a carrier member;
"optical" applies not only to visible light but also to ultra-violet or infra-red radiations.
This subclass covers, as far as processes are concerned, only processes characterised by the use or manipulation of apparatus classifiable per se in this subclass.
This subclass covers the production of permanent directly-visible pictures in conformity with an original picture or document, using an imagewise distribution of an electric or magnetic quantity, such as a charge pattern, an electric conductivity pattern, or a magnetic pattern.
This subclass does not cover:
use of electric signals for the transmission of the picture information from the original to the reproduction, i.e. pictorial communication, which is covered by subclass Fulltext... Hierarchy... Expanded...H04N;
production of pictures by heat patterns exclusively, not using an electrostatic or magnetic pattern, which is covered by group Fulltext... Hierarchy... Expanded...B41M 5/00;
production of prints by transferring ink from a printing form to a printing surface, without physical contact and using the force of an electrostatic field, which is covered by subclass Fulltext... Hierarchy... Expanded...B41M.
This subclass covers means for producing a record of the phase and amplitude information of a wave-front, which information can be used to reconstruct the original wave-front, or means to reconstruct the original wave-front from a record containing the phase and amplitude information of the wave-front.
