Direct backlight modules using diffraction optical elements are provided. A direct backlight module includes a light source and a diffraction optical element, wherein the diffraction optical element is disposed above the light source. By properly arranging the phase function, the diffraction optical element can substantially modulate the wavefront of the light emitted from the light source and control light distribution as well as light direction.

Backlight modules using diffraction optical elements

An anti-counterfeit method and system by using a nano metal grating, wherein an object to be recognized is formed with the nano metal grating. During the recognition process, an incidental light is applied on the metal grating. In response to the incidental light, the metal grating has its specific optical incidence and reflection characteristics. The object is then identified whether it is genuine or fake by observing the refraction light passing through and reflection light reflected from the metal grating. Further, the incident light beam can be polarized to generate polarized light beams and then irradiated on the metal grating, whereafter the recognition of the object is performed by observing the reflection and refraction lights of the irradiated polarized light beam. The recognition further can be accomplished by rotating the metal grating, thus the intensity of the refraction and reflection lights will accordingly be changed, thereby identifying the object.

Anti-counterfeit method and system by using a nano metal grating

An apparatus for forming a nano grating device to film nano-scale interference fringes by holography in order to makes a nano-scale meshed structure is disclosed. A beam emitted form a light source passes subsequently through a beam splitter and two reflectors to reach at symmetrically mounted light emitting modules. The light emitting modules generate two beams passing along the same optical paths and then projecting on a photosensitive substrate that is attached on a hemi-sphere lens. Thus, a first set of interference fringes are formed. Then, the substrate rotates with an angle and then is subjected to exposure to form a second set of interference fringes crossing the first set of interference fringes. Thereby, a nano-scale meshed structure is obtained.

A micro fluorescent electrophoresis (EP) detection system for detecting fluorescent EP is disclosed. The size of the system is greatly minimized for carrying. The invention uses a laser diode with a cylindrical lens to perform light source detection. A probe is provided to receive excited light produced by the probed object and to convert it into an electronic signal for detection. This does not only lower the cost, but also largely reduce its size for the patient's convenience of carrying and self-testing.

A diffractive anti-counterfeiting tag structure with capabilities of naked-eye inspection and machine inspection and its method of manufacture. The anti-counterfeiting tag structure has a naked-eye inspection component and a machine inspection non-grating diffractive component. The naked-eye inspection component and the non-grating diffractive component are formed on separate mold-boards and then joined together to form a mold-board using a board-joining technique. Alternatively, a plurality of naked-eye inspection blocks and a plurality of non-grating diffractive blocks are randomly mixed together to form a pixel-like diffractive anti-counterfeiting tag.
