Abstract:
A multiple reflective mirrors module utilized in an optical engine, the multiple reflective mirrors module comprising:a first tilting reflective mirror; a second tilting reflective mirror disposed opposite the first tilting reflective mirror, an incident light of the second tilting reflective mirror being reflected by the second tilting reflective mirror to form a first reflected light transmitted to the first tilting reflective mirror, wherein the first reflected light is formed with an angle variation 2&thgr;1+2&thgr;2 when the first tilting reflective mirror rotates an angle &thgr;1 and the second tilting reflective mirror rotates an angle &thgr;2; and a third tilting reflective mirror disposed opposite the first tilting reflective mirror, the first reflected light being reflected by the first tilting reflective mirror, transmitted to the third tilting reflective mirror, and then reflected by the third tilting reflective mirror to form a second reflected light, wherein the second reflected light is formed with an angle variation 2&thgr;1+2&thgr;2+2&thgr;3 when the third tilting reflective mirror rotates an angle &thgr;3.
