Latest Patents
One of Yina Chang's latest patents is titled "System and method for curved light sheet projection during two-photon polymerization." This invention discloses a laser-based manufacturing system designed for fabricating non-planar three-dimensional layers. The system utilizes a laser to produce a beam with multiple optical wavelengths. An optically dispersive element is employed to split the beam into distinct components, each with spatially separated optical spectral components. A phase mask modifies one of the beam components, which is then focused into a non-planar light sheet for part fabrication.
Another notable patent is "Systems and methods for dicing samples using a Bessel beam matrix." This method involves generating a Bessel beam matrix that includes multiple Bessel beams arranged in a matrix form, according to a predetermined dicing layout. The focus position of each Bessel beam is controlled, allowing for simultaneous focusing at the respective positions within the sample for effective dicing.
