Optical configurations for head worn computing

Abstract

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

We claim: 
     
         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 that is above the user's eye 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.
