Abstract
An augmented reality display device (such as a head mounted device) includes a partially transparent and partially reflective lens, a laser light source, a radio frequency source, a display controller, an acousto-optical modulator, and a microelectromechanical (MEMS) device. The laser light source generates light. The radio frequency (RF) source generates a RF signal. The display controller generates a synchronization signal. The acousto-optical modulator receives at least a portion of the light, modulates the light based on the RF signal, and provides modulated light. The MEMS device receives the synchronization signal from the display controller and reflects the modulated light towards the partially transparent and partially reflective lens. The MEMS device determines a direction in which the modulated light reflects based on the synchronization signal and the partially transparent and partially reflective lens reflecting the modulated laser light towards an eye of a user of the augmented realty display device.
