Abstract

Aspects of the present invention relate to optical systems in head worn computing.

Claims

1. A head worn computer, comprising

a. A housing adapted to be worn on the head of a user, wherein the housing is adapted to hold an optical system;

b. The optical system adapted to present digital content to a visual field of the user, when the user is wearing the head worn computer, the optical system also adapted to be transmissive such that the user can view a surrounding environment through the optical system;

c. The optical system further comprised of a DLP positioned to provide image light from a position in the housing into an optical system that directs the image light to the user'"'"'s eye; and

d. The housing further comprising a light absorber positioned in proximity to a DLP “

off”

state light path to collect and absorb the “

off”

pixel light.
