An optical system for a projector and an imaging method thereof. A light beam from a light source passes through a first lens set and a second lens set sequentially. The light beam having passed through the second lens set is reflected by a first mirror to pass through the second lens set again and arrived at an imaging device. The light is reflected from the imaging device to a projection lens set to project the light beam onto a screen.
