| 20080316878 | METHOD FOR MEASURING THICKNESS AND MEASURING DEVICE USING THE SAME - A method for measuring thickness of a transparent layer and a measuring device using the same are provided. The transparent layer has a first face, a second face and a normal direction. The method includes the following steps. First, a light beam with a focal point is emitted to the transparent layer. Next, a focus error signal (FES) is generated according to a refracted beam of the light beam. Then, the focal point is moved along the normal direction and passes through the first face and the second face. The FES converts into a first focus error curve and a second focus error curve respectively when the focal point passes through the first and the second face. Afterwards, the thickness of the transparent layer is obtained according to the first focus error curve and the second focus error curve. | 12-25-2008 |
| 20090032692 | Apparatus of generating an optical tweezers with momentum and method thereof and photo-image for guiding particles - 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. | 02-05-2009 |
| 20090040620 | DISK STRUCTURE, MANUFACTURING METHOD THEREOF AND OPTICAL TWEEZERS DEVICE USING THE SAME - 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. | 02-12-2009 |
| 20090047462 | THREE-LEVEL RECORDING PHASE-CHANGE OPTICAL DISC - A three-level recording phase-change optical disc including a first recording layer, a second recording layer, a third recording layer, a reflective layer, and a dielectric layer is provided.

| 20090051999 | Optical tweezers controlling device - 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. | 02-26-2009 |
| 20090052038 | Apparatus and method for changing optical tweezers - 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. | 02-26-2009 |
