OPTICAL SYSTEMS INCLUDING ANGLE CONTROL FILMS

An optical system includes a lens layer having a first major surface including first and second microlenses and a first light absorbing layer. The light absorbing layer defines first and second through openings with a one-to-one correspondence between the first and second microlenses and respective...

description An optical system includes a lens layer having a first major surface including first and second microlenses and a first light absorbing layer. The light absorbing layer defines first and second through openings with a one-to-one correspondence between the first and second microlenses and respective first and second through openings. Each pair of first microlens and first through opening centered on a first optical axis makes a first angle with a normal to the first light absorbing layer. Each pair of second microlens and second through opening centered on a second optical axis makes a second angle, different than the first angle, with the normal to the first light absorbing layer. A light source emits light incident on the first major surface side. The emitted light includes first and second light beams carrying respective first and second information and propagating substantially parallel to the first and second optical axes, respectively.
