Abstract:
A head-mounted display including a first optical system is described. The first optical system includes a partial reflector and a multilayer reflective polarizer disposed adjacent to and spaced apart from the partial reflector. The multilayer reflective polarizer is curved about orthogonal first and second axes and includes at least one layer that is substantially optically uniaxial at at least one location. Each chief ray that passes through the first optical system is first incident on the multilayer reflective polarizer at an angle of incidence less than 30 degrees.

Claim (Index 1):
A head-mounted display comprising a first optical system, the first optical system comprising:\n a first partial reflector having an average optical reflectance of at least 30% in a desired plurality of wavelengths; and a first multilayer reflective polarizer disposed adjacent to and spaced apart from the first partial reflector, the first multilayer reflective polarizer substantially transmitting light having a first polarization state and substantially reflecting light having an orthogonal second polarization state, the first multilayer reflective polarizer curved about orthogonal first and second axes, at least one first location on the first multilayer reflective polarizer having a radial distance, r1, from an optical axis passing through an apex of the first multilayer reflective polarizer and a displacement, s1, from a plane perpendicular to the optical axis at the apex, s1/r1 being at least 0.1 and less than 0.8, wherein the first multilayer reflective polarizer comprises at least one layer substantially optically uniaxial at at least one location, and wherein each chief ray that passes through the first optical system is first incident on the first multilayer reflective polarizer at an angle of incidence less than 30 degrees.
