Abstract
A holographic skew mirror has a reflective axis, or skew axis, that can be tilted with respect to its surface normal. Tilting the skew axis in two dimensions with respect to the surface normal expands the holographic skew mirror's possible field of view, e.g., to 60 or more. These additional angles can be accessed using an out-of-plane writing geometry with matched total internal grazing extension rotation (TIGER) prisms.
