An optical display system is disclosed having a preferred application in a helmet mounted heads-up display. The display system includes an image source (42-46) for generating an image which includes a plurality o fields sequentially displayed by the image source to form the image with a two-dimensional array of pixels forming each field and the fields having a spatially modulated light intensity. An image display (50) is coupled to the image source for displaying the fields. The image display produces for each field a two-dimensional display having a fixed number of light emitting points (65) which are disposed along each dimension of the two-dimensional array with each light emitting point being spaced apart from adjacent light emitting points by a fixed distance. An actuator (52) is provided for moving the light emitting points in unison in a repeated pattern relative to a field of view of the displayed image with motion of each of the light emitting points along two axes during the repeated pattern delineating an area which is a fraction of an area of the displayed image produced by the image display. Movement of the light emitting points through successive positions of the repeated pattern is synchronized with the successive display of individual fields by the image source.
