摘要:
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.

The present invention provides a reversible thermochromic optical disc capable of forming a pattern thereon by an optical pick-up unit of an optical disc drive. The reversible thermochromic optical disc includes a substrate and a reversible thermochromic dyestuff. The substrate has a label surface. The reversible thermochromic dyestuff coated on the label surface has a hysteresis characteristic upon change of a temperature, and changes between a colored state and a decolored state, wherein the color of the reversible thermochromic dyestuff responds to heat of a laser beam emitted by the optical pick-up unit to form the pattern.

A computer implemented method and system provides a mobile application development platform (MADP) for dynamically creating a healthcare provider specific customizable composite mobile application (CCMA) and monitoring healthcare elements of a healthcare recipient using the CCMA. The MADP is accessible by a healthcare provider device and a healthcare recipient device via a network. The MADP stores multiple template objects, for example, sub-applications that perform tasks for monitoring the healthcare elements in an application management database (AMD). The MADP acquires a selection of one or more template objects and one or more dynamic content objects defined by a healthcare provider and dynamically creates the CCMA by integrating the selected template objects and dynamic content objects. The MADP stores the CCMA in the AMD. The CCMA facilitates communication between the healthcare provider device and the healthcare recipient device for monitoring the healthcare elements of the healthcare recipient.

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.
