Processes or apparatus for producing holograms (G03H1/26 takes precedence)

Introduced: July 1974

Title

Titles differ between systems:

IPC: Processes or apparatus for producing holograms

CPC: Processes or apparatus for producing holograms (G03H1/26 takes precedence)

Full Title

Full titles differ between systems:

IPC:

Holographic processes or apparatus using light, infrared, or ultraviolet waves for obtaining holograms or for obtaining an image from them; Details peculiar thereto > Processes or apparatus for producing holograms

CPC:

Holographic processes or apparatus using light, infrared or ultraviolet waves for obtaining holograms or for obtaining an image from them; Details peculiar thereto > Processes or apparatus for producing holograms (G03H1/26 takes precedence)

Of 12 combined children, 6 exist in both systems.

6 codes are CPC-only extensions.

2 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 1974.
