Patent attributes
A parallel beam flexure mechanism (“PBFM”) for adjusting an interpupillary distance (“IPD”) of an optical device is disclosed. The PBFM includes a plurality of flexures, a mounting platen, an optical payload, and a horizontal translation mechanism. The mounting platen has a first end and a second end, where the mounting platen is attached to a first set of flexures that are in a parallel arrangement to a second set of flexures attached to a frame of an optical device, such as a head mounted display. The optical payload and horizontal translation mechanism are attached to the mounting platen, where the horizontal translation mechanism is configured to translate the mounting platen in a horizontal direction by bending the flexures, thereby adjusting the IPD of the optical device.
