Abstract
An optical device for projecting light beams that is able to interact with a pixelated light source comprising a plurality of selectively activatable emitting elements. The device successively includes, in the direction of the path of the light rays, a first optical unit, a pupil and a second optical unit. The first optical unit includes an output diopter located at a first distance (d1) from the pupil, and the second optical unit includes an input diopter interface located at a second distance (d2) from the pupil, the second distance (d2) being substantially identical to the first distance (d1). The first unit includes a converging lens, and the second unit includes a doublet of lenses one of which is made of flint glass and the other of which is made of crown glass.
Claims21
An optical device comprising:
- a first optical unit, a pupil and a second optical unit arranged in succession a traveling direction of light rays received by the optical device, wherein:
- the first optical unit comprises an exit dioptric interface located at a first distance (d1) from the pupil,
- the second optical unit comprises an entrance dioptric interface located at a second distance (d2) from the pupil,
- the second distance (d2) is substantially identical to the first distance (d1),
- the first optical unit comprises a convergent lens,
- the second optical unit comprises a first lens doublet,
- one lens of the first lens doublet is made of flint glass and is divergent, and
- the other lens of the first lens doublet is made of crown glass and is convergent.
