Abstract: Systems, devices, and methods for field shaping in wearable heads-up displays (WHUD) with laser projectors are described. A WHUD includes a support structure carrying a laser projector, a field shaper optic, and a transparent combiner to combine the projected laser light and environmental light. The laser projector generates a laser light having a field. The laser light is scanned through the field shaper optic and over the transparent combiner. The field shaper optic heterogeneously varies the focal length of the laser light depending on the laser light properties to alter the field of the laser light to approximately match a shape of the transparent combiner. The transparent combiner redirects the laser light to a field of view of a user to create a focused image at an eye of the user.

Abstract: An image display device includes a light source that emits a light beam, a screen, a scanning section that scans the screen with the light beam, an optical system, a drive section, and a screen drive circuit. The optical system generates a virtual image by using the light beam that has passed through the screen. The drive section moves the screen at least in parallel to a travel direction of the light beam. The screen drive circuit contains a drive signal table that stores an information group for use in generating a drive signal tailored to stop the screen at different stop locations over different stop periods. The screen drive circuit selects first information in the drive signal table which is associated with displaying of an image and supplies the drive section with a first drive signal generated from the first information.

Abstract: An eye projection system is disclosed, including an image generator and an eye projection optical module. The image generator is adapted to obtain data indicative of an image, produce a plurality of light beam portions corresponding to pixels of the image, adjust the intensity of each light beam portion in accordance with a value of a pixel of the image corresponding thereto and direct the light beam portion to propagate along a general optical propagation path towards the eye projection optical module with a projection angle αscn, relative to the general optical propagation path, which is determined in accordance with a location of the respective pixel in the image. The eye projection optical module includes a gaze tracking deflector responsive to input signals indicative of a gaze direction β of a user eye and configured and operable to deflect the general optical propagation path of the light beam portions towards the location of the pupil of the user eye associated with the gaze direction β. The general optical propagation path is deflected such that the light beam portions incident on the pupil with pupil incidence angles αin with respect to a line of sight of the pupil, where the pupil incidence angles αin correspond to the projection angles αscn. The system thereby provides direct projection of the image onto the retina of the eye at a specific location on the retina regardless of the gaze direction β of the eye.
