Image Projection System
The microprojector is the most vital system in the glasses, and it includes several different internal components to produce an image in someone’s view. The graphic to the right shows the basic functionality.
First, the projected light is generated by a light blue laser diode in the frames of the glasses.
Then, the light shoots out onto a quick-moving, tilting mirror, often referred to as a “MEMS mirror.” The MEMS mirror is powered electrostatically with resonating motion to deflect these rays at high sensitivity and frequency.
The MEMS mirror redirects the rays onto a holographic film/coating on the right lens which subsequently reflects the light into someone’s eye, directly projecting it onto the retina. In this way, the user sees a graphical overlay on their vision.
