An imaging method. A light beam passes through a first lens set, a second lens set, an imaging device and a projection lens set. The light beam is focused in a first position. The focused light beam converges in a first relay position via the first lens set and in a second relay position via the second lens set. The optical path from the first position to the principal plane of the first lens set is defined as a first optical path, and the principal plane of the second lens set to the second relay position as the fourth optical path. The length of the first optical path is longer than twice the focal length of the first lens set, and the length of the fourth optical path is longer than twice the focal length of the second lens set.

Optical imaging method and projector utilizing the same

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.
