A method of making an optical disc is disclosed, in which, a flexible imprint mold is made from a fluid-state flexible silicone and has a reversal pattern of a first pattern on a surface. Also, a substrate is provided and has a second pattern on the surface with a semi-reflective layer deposited thereon. A dye or UV curable resin layer is formed on the semi-reflective layer. The flexible imprint mold is used to imprint the dye or UV curable resin layer and allowed to stay on it. After the dye or UV curable resin layer is cured, the flexible imprint mold is released from the cured dye or UV curable resin layer, such that the dye or UV curable resin layer has the first pattern.

The present invention provides a system for recording an image onto a label layer of an optical disc. The optical disc also includes a data layer on which a plurality of predetermined address codes is marked. The system essentially includes a multi-focal lens module for dividing a laser beam emitted by an optical pick-up unit into a first beam portion and a second beam portion. The first beam portion is focused on the data layer to locate a first position by retrieving the predetermined address codes. The second beam portion is focused on the label layer to record the image at a second position opposite to the first position.

An apparatus of generating an optical tweezers with momentum and method thereof and an optical tweezers photo-image for guiding particles are provided. The apparatus generates at least one optical tweezers on an examined object that carries at least one particle. The apparatus includes a laser source, a diffractive optical element and a convergent lens. The laser beam from the laser source passes through the diffractive optical element to produce a diffractive pattern. The laser beam is then received by the convergent lens and then to be focused on a plane of the examined object. The optic axis of the convergent lens is substantially not perpendicular to the plane of the examined object, so that the laser beam is projected onto the plane of the examined object in a skewed manner for providing a lateral momentum to move the particle.

A three-dimensional image display includes a liquid crystal display panel, a lenticular layer, and a backlight module, wherein the lenticular layer is disposed on the liquid crystal display panel to separate images generated by the liquid crystal display panel. The backlight module includes a light emitting device and at least one brightness enhancing film. The liquid crystal display panel accepts light from the backlight module and generates a plurality of images. Prisms and lenses are disposed on the brightness enhancing film and the lenticular layer, respectively, wherein orientations of prisms and lenses cross each other. The three-dimensional image display makes the traveling direction of light more perpendicular to the surface of liquid crystal display panel in order to reduce the crosstalk between adjacent images.

A disk structure is disposed in an optical tweezers device including a light source for producing incident laser light. The disk structure includes a first substrate, a second substrate and a reflective layer. The second substrate is disposed with respect to the first substrate. One of the first substrate and the second substrate has at least one flow path. The reflective layer, which is adhered to the second substrate, is disposed between the first substrate and the second substrate. After the incident laser light passes through the first substrate and then reaches the reflective layer, the incident laser light is reflected back as reflective laser light by the reflective layer to form reflective laser light. A tweezers light field is formed in the flow path by both the reflective laser light and the incident laser light.

An optical tweezers controlling device including a light source, an objective lens and a focus adjusting unit is provided. The focus adjusting unit disposed between the light source and the objective lens includes a mirror set and a zoom lens set. The mirror set has at least a mirror. The mirror is rotatable such that after a light of the light source is projected to the mirror, the reflective direction of the light reflected from the mirror is changeable. The zoom lens set has at least a zoom lens disposed in accordance with the mirror. By rotating the mirror or changing the focal length of the zoom lens, the focusing location of the light changes on the focal plane of the objective lens or in the front or the rear of the focal plane.

An apparatus and a method for changing optical tweezers are provided. The apparatus includes a diffractive optical element (DOE), a mask unit and an objective lens. The DOE includes a plurality of phase delay patterns. The mask unit includes a plurality of mask patterns that correspond to the phase delay patterns, respectively, wherein at least a portion of the mask patterns are complementary. A laser beam passing through each phase diffractive pattern correspondingly passes through each mask pattern to generate a compound diffractive pattern. The objective lens receives the compound diffractive pattern and focuses it on an examining object to form an optical tweezers.
