Abstract
The image projection and capture apparatus for projecting an image beam to display an image on a screen and sensing a sensing beam from the image on the screen, the image projection and capture apparatus includes a light source, a light valve, a projection lens, an image capture lens, a dichroic unit, and an image sensor. The light source provides an illumination beam. The light valve is capable of converting the illumination beam to the image beam. The projection lens has a first optical axis. The image capture lens has a second optical axis. The first optical axis and the second optical axis are collinear. The dichroic unit is disposed between the projection lens and the image capture lens. The image sensor is disposed on a light path of the sensing beam.
