Publication number: 20240144708Abstract: An examination system is provided. The examination system includes an optical detector and analyzer. The optical detector emits a detection light source toward a target object and detects a respondent light which is induced from the target object in response to the detection light source to generate image data. The image data indicates a detection image. The analyzer receives the image data and determines which region of the target object the detection image belongs to according to the image data. When the analyzer determines that the detection image belongs to a specific region of the target object, the analyzer extracts at least one feature of the image data to serve as a basis for classification of the specific region.Type: ApplicationFiled: January 4, 2024Publication date: May 2, 2024Inventors: Chih-Yang CHEN, Pau-Choo CHUNG CHAN, Sheng-Hao TSENG

Patent number: 8258461Abstract: 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.Type: GrantFiled: July 30, 2008Date of Patent: September 4, 2012Assignee: Raydium Semiconductor CorporationInventors: Long Hsu, Cheng-Hsien Liu, Sheng-Yang Tseng, William Wang, Chung-Cheng Chou, Fung-Hsu Wu, Chen Peng, Ta-Yuan Lee

Patent number: 7838819Abstract: An apparatus of generating optical tweezers with momentum is provided for providing optical tweezers with a first momentum on a test piece. The apparatus comprises a laser source, a diffractive optical element (DOE) and a lens. The laser source is for outputting a laser beam. The DOE has a first phase-delay picture, and the laser beam forms a diffraction pattern after passing the first phase-delay picture. The lens is for receiving and focusing the diffraction pattern on the test piece to form the first optical tweezers with the first momentum. The lens has an optical axis intersecting the DOE at an optical intersection point, a geometric center of the phase-delay picture has a displacement vector relative to the optical intersection point and a direction of the first momentum is related to a direction of the displacement vector.Type: GrantFiled: January 24, 2008Date of Patent: November 23, 2010Assignee: Raydium Semiconductor CorporationInventors: Long Hsu, Cheng-Hsien Liu, Sheng-Yang Tseng, Chung-Cheng Chou, Wai William Wang, Fung-Hsu Wu, Chen Peng, Ta-Yuan Lee

Patent number: 7829839Abstract: An optical tweezers lifting apparatus is provided. The optical tweezers lifting apparatus includes an optical tweezers and a particle-lifting device. The particle-lifting device includes a substrate and a plurality of electrodes that are disposed on the bottom of a flow path in the substrate. When a dielectrophoresis (DEP) solution with a plurality of floating particles is conducted into the flow path and upon those electrodes and a voltage is applied to these electrodes, these particles would be driven by a negative DEP force to move upward to a specific depth in the flow path. Meanwhile, the optical tweezers of the apparatus is selectively focused at the specific depth in the flow path.Type: GrantFiled: October 17, 2008Date of Patent: November 9, 2010Assignees: Raydium Semiconductor Corp.Inventors: Cheng-Hsien Liu, William Wang, Long Hsu, Chung-Cheng Chou, Sheng-Yang Tseng, Chen Peng, Fung-Hsu Wu, Ta-Yuan Lee

Patent number: 7804058Abstract: 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.Type: GrantFiled: August 6, 2008Date of Patent: September 28, 2010Assignee: Raydium Semiconductor CorporationInventors: Long Hsu, Cheng-Hsien Liu, Sheng-Yang Tseng, Ai-Tang Chang, Chung-Cheng Chou, William Wang, Fung-Hsu Wu, Chen Peng, Ta-Yuan Lee

Patent number: 7786432Abstract: 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.
