by electromagnetic radiation, e.g. optical sensing; by corpuscular radiation

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Methods or arrangements for sensing record carriers > by electromagnetic radiation, e.g. optical sensing; by corpuscular radiation

CPC:

Methods or arrangements for sensing record carriers, (methods or arrangements for marking the record carrier in digital fashion G06K1/00; pattern recognition G06F18/00; arrangements for image or video recognition or understanding G06V10/00; character recognition, recognising digital ink or document-oriented image-based pattern recognition G06V30/00) > by electromagnetic radiation, e.g. optical sensing; by corpuscular radiation

CPC subdivides this area 5x more granularly than IPC with 7 additional codes.

7 codes are CPC-only extensions.

Note: 4 CPC extensions are marked as secondary classification only.
