Assignee: SAINT-GOBAIN GLASS FRANCE
Field: Surface technology, coating (Chemistry)
Classification: CPC B  G | IPC B  G

Claim 0:
1. A composite pane, comprising:
an outer pane and an inner pane that are joined to one another via at least one thermoplastic intermediate layer, and
at least one light sensor with at least one light-sensitive surface that is arranged between the outer pane and the inner pane,, wherein
the light-sensitive surface faces the outer pane and
a holographic optical element is arranged between the light-sensitive surface and the outer pane,
the holographic optical element is implemented as a hologram for incident-angle-dependent diffraction of the incident light,
the holographic optical element is implemented such that it directs light incident on the outer pane in a first angle of incidence range alpha at least partially onto the light-sensitive surface and directs light incident in a second angle of incidence range beta next to the light-sensitive surface, and
the first angle of incidence range alpha comprises all angles of incidence phi relative to an orthogonal of the holographic optical element from 0° to 60°; and/or the second angle of incidence range beta comprises all angles of incidence phi relative to the orthogonal of the holographic optical element from −90° to 0°.
