A head-up display system (10, 46) comprising: a microprojector (16, 16'); a near-eye viewer optic, comprising: a forward viewer optic (22, 22') aligned to a forward field-of-view of an eye (40, 40') of a user; a peripheral viewer optic (24, 24') aligned to a peripheral field of view of the eye (40, 40') of the user; a redirection optic (26, 26') switchable electronically between first and second optical states, the redirection optic (26, 26') configured to receive a display image from the microprojector (16, 16'), to convey the display image, in the first optical state, to the forward viewer optic (22, 22'), and to convey the display image, in the second optical state, to the peripheral viewer optic (24, 24'); and a fold reflector (34, 34'), wherein a position of the redirection optic and the fold reflector is adjustable relative to the forward viewer optic and peripheral viewer optic, and wherein adjustment of the position causes the display image to be shifted laterally in the near-eye viewer optic, thereby enabling adjustment of an interpupilary distance in the display system; and an electronic controller configured to, during a first interval, switch and maintain the redirection optic (26, 26') in the first optical state and cause the microprojector (16, 16') to form the display image based on forward image data, the electronic controller configured to, during a second interval, switch and maintain the redirection optic (26, 26') in the second optical state and cause the microprojector (16, 16') to form the display image based on peripheral image data, wherein the forward and peripheral image data encode display imagery of an extended field of view. a microprojector (16, 16'); a near-eye viewer optic, comprising: a forward viewer optic (22, 22') aligned to a forward field-of-view of an eye (40, 40') of a user; a peripheral viewer optic (24, 24') aligned to a peripheral field of view of the eye (40, 40') of the user; a redirection optic (26, 26') switchable electronically between first and second optical states, the redirection optic (26, 26') configured to receive a display image from the microprojector (16, 16'), to convey the display image, in the first optical state, to the forward viewer optic (22, 22'), and to convey the display image, in the second optical state, to the peripheral viewer optic (24, 24'); and a fold reflector (34, 34'), wherein a position of the redirection optic and the fold reflector is adjustable relative to the forward viewer optic and peripheral viewer optic, and wherein adjustment of the position causes the display image to be shifted laterally in the near-eye viewer optic, thereby enabling adjustment of an interpupilary distance in the display system; and a forward viewer optic (22, 22') aligned to a forward field-of-view of an eye (40, 40') of a user; a peripheral viewer optic (24, 24') aligned to a peripheral field of view of the eye (40, 40') of the user; a redirection optic (26, 26') switchable electronically between first and second optical states, the redirection optic (26, 26') configured to receive a display image from the microprojector (16, 16'), to convey the display image, in the first optical state, to the forward viewer optic (22, 22'), and to convey the display image, in the second optical state, to the peripheral viewer optic (24, 24'); and a fold reflector (34, 34'), wherein a position of the redirection optic and the fold reflector is adjustable relative to the forward viewer optic and peripheral viewer optic, and wherein adjustment of the position causes the display image to be shifted laterally in the near-eye viewer optic, thereby enabling adjustment of an interpupilary distance in the display system; and an electronic controller configured to, during a first interval, switch and maintain the redirection optic (26, 26') in the first optical state and cause the microprojector (16, 16') to form the display image based on forward image data, the electronic controller configured to, during a second interval, switch and maintain the redirection optic (26, 26') in the second optical state and cause the microprojector (16, 16') to form the display image based on peripheral image data, wherein the forward and peripheral image data encode display imagery of an extended field of view.
