Paper Abstract

A Retinal Scanning Display (RSD) utilizes scanning mirrors and optics to produce a flying spot that forms a raster image directly on the retina of the eye. A high-frequency resonant horizontal scanner and a linear ramp vertical scanner function together to produce video typically at a 60Hz frame rate. Although the raster can be formed by Unidirectional Writing (using only the forward half-period of the horizontal scan function) and one flying spot, it is desirable to achieve Bidirectional Writing (utilizing the full period of the Horizontal scan function) with multiple scanned spots for the purpose of increased efficiency of the display with a limited horizontal scanner frequency. This paper will look at the limitations and requirements for the scanning functions to make this possible.
