Abstract
An apparatus includes a light source configured to produce light and a prism. The apparatus also includes freeform optics optically coupled between the light source and the prism, the freeform optics configured to direct the light towards the prism and eyepiece optics optically coupled to the prism. Additionally, the apparatus includes a spatial light modulator (SLM) optically coupled to the prism, the prism configured to direct the light towards the SLM, the SLM configured to modulate the light to produce modulated light, and the prism configured to direct the modulated light towards the eyepiece optics.
