A manufacturing method of an optical element applied to a miniature microscope comprises the steps of: emitting a signal light and a reference light to an optical material; and forming a plurality of gratings on the optical material by interfering the signal light and the reference light. A miniature microscope is also disclosed.

A reading device includes a spatial light modulator, a zoom lens set, an object lens, an image sensor, and an adjusting module. The spatial light modulator provides a reading beam. The zoom lens set forms the reading beam into a real image. The object lens focuses the real image onto a collinear holographic storage medium and thus produces a diffraction signal. The image sensor converts the diffraction signal into an electric signal. The adjusting module adjusts the optical magnification of the zoom lens set according to the quality of the diffraction signal.
