“…We also developed proprietary stamping techniques that can produce mirror finishes in metallic optical benches. 19 The mirrors can be as small as a few hundred micrometers in size with sub-micron accuracy and surface finishes as low as R a 4 nm without secondary processing. Figure 3(a) shows exemplary metrology data demonstrating that sub-micrometer form error in individual micro freeform mirrors and an 8 x 1 array of mirrors stamped in a set of MOBs (as seen in photo in 1(a)).…”

Optical Architectures for Displays and Sensing in Augmented, Virtual, and Mixed Reality (AR, VR, MR) IV

Augmented, virtual, and mixed reality (XR) displays require miniature light engines that can be worn near-theeye. Laser beam scanner (LBS) architectures use light from a hermetically-sealed laser beam module (LBM) and scan the light with a MEMS mirror into a combiner. This paper presents an improved method for packaging a red, green, and blue (RGB) LBM using stamped mirror arrays that fold the light beam, correct beam shape, and redirect beam propagation to a MEMS mirror. The mirror array simplifies the optical path and eliminates passive components like dichroic filters and refractive lenses such as those used for slow-axis and fast-axis correction. This new approach reduces the size, weight, and cost of LBMs for XR applications.
