摘要:
The invention discloses a device for animating facial expression. The device includes at least one resilient member and at least one actuator. The resilient member is regarded as a facial feature on a face, and the resilient member has a first end and a second end. The first end of the resilient member is rotatably and/or movably attached onto the face. The actuator is used for actuating the first end of the resilient member to rotate, so that the facial feature is capable of exhibiting various facial expressions on the face, wherein the facial feature can be eyebrow, upper eyelid, lower eyelid, upper lip or lower lip.

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.

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.

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.

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.
