Abstract
A double-image projection device includes a laser projector, a semi-reflection mirror, and an ear canal model. The semi-reflection mirror is located in front of the laser projector; while the laser projector includes a MEMS (micro-electromechanical system) scanner for projecting scanning light beams, such that the scanning light beams is projected onto an imaging plane as a large image through transmitting through the semi-reflection mirror. The ear canal model is located in a reflective light path of the semi-reflection mirror, with its front end provided with a viewing port, and with its rear end provided with an ear drum piece, such that the scanning light beams emitted by the laser projector is projected onto the ear drum piece of the ear canal model a small image, through reflecting by the semi-reflection mirror.
