Abstract
The present invention provides an optical imaging processing system. The system includes a screen, an incident light source, and at least one optical transmission medium, where the optical transmission medium is disposed in an optical imaging path in which the incident light source is emergent and is projected to the screen; an light incident face of the optical transmission medium faces the incident light source, and an light exiting face of the optical transmission medium faces the screen, where at least one cavity is included between the light incident face and the light exiting face of the optical transmission medium, and a cross-section shape of the cavity is an isosceles trapezoid; and the cavity includes a light transmission area and a light blanking area used for object accommodation, and the optical imaging path bypasses the light blanking area and penetrates through the optical transmission medium through the light transmission area.
