A simple system for head-up display based on the separation of the ocular fields. When the right eye's (RE, 22) field of view (RFOV) is separated from that of the left eye, (LE, 24) the possibility of parallactic splitting of the displayed image is eliminated. Such a configuration is particularly useful where a two-dimensional display image is superimposed on a three-dimensional view having considerable depth, so that disturbances due to parallax effects are unavoidable. Preliminary design for automotive applications suggests an instantaneous display field consisting of two 12 mrad vertical strips, symmetrically located +/- 2.2 degrees about the meridional plane. Such a field allows free head movement within a frame of 40.0 mm up and down, and side to side. For observation of at least half of the field, that is, viewing at least one strip or the other, the horizontal span of head movement would be expanded to about 195 mm. |
