Abstract
A transparent rotating device comprising a shaft, a transparent rotating assembly and a motor is provided. The transparent rotating assembly includes at least one first transparent sheet and at least one second transparent sheet that are annularly and alternatively arranged around a shaft. A motor is connected to the shaft, wherein the first transparent sheet and the second transparent sheet sequentially enter the transmission path of the image beam. The angle at which the first transparent sheet is inclined with respect to the shaft is different from the angle at which the second transparent sheet is inclined with respect to the shaft. The image beam penetrates the first transparent sheet to be deflected and transmitted to a first position, and the image beam penetrates the second transparent sheet to be deflected and transmitted to a second position.
