The invention belongs to the field of
projector and camera manufacturing, and particularly discloses an
optical switch array and an
optical path device with the functions of projection and camera shooting formed by the
optical switch array. The
optical switch array comprises an optical switch chain which is arranged along the y axis in the three-dimensional rectangular coordinate
system and a plurality of T-shaped optical switch chains which are arranged parallel to the z axis. The
optical path device with the functions of projection and camera shooting comprises a processor (1), a driving module (2), a display
light source (3), a photoconductor unit (4), a light path separation unit (5), a divergent unit (6) and a lens module (7). The
optical path device with the functions of projection and camera shooting is characterized in that the optical device is further provided with the optical switch array (8), and through controlling of the status of each 'T'-shaped optical switch in the optical switch array (8), direct
projection display and scenery shooting are achieved. According to the optical switch array and the optical path device with the functions of projection and camera shooting, the structure is simple, the running
power consumption is low, service life is long, the display color
gamut is about the same as a
laser television, the
image quality is high, and the function of the projection and the function of the camera shooting are integrated.
