Abstract:
1. In a display system comprising an oscillating high frequency mirror for generating scan lines for an image frame and an oscillating low frequency mirror for positioning said scan lines of said image frame, a method of generating at least two frames of images for each cycle of said oscillating low frequency mirror, comprising the steps of: providing a cyclic drive signal having positive and negative going portions to said low speed mirror for positioning said scan lines; generating a first initiate signal during said cyclic drive signal; generating a first arming signal after a first selected time delay and in response to said first initiate signal; generating a second arming signal after a second selected time delay; generating said scan lines as said low frequency mirror travels in a first direction, and in response to said first arming signal; and generating said scan lines as said low frequency mirror travels in a second direction opposite said first direction and in response to said second arming signal.
