Latest Patents

Huang's latest patents include a "Lithography pupil shaping optical system and method for generating off-axis illumination mode." This invention comprises an illumination mode generation unit, a rotatable wave plate, a polarization beam splitter unit, a ring I generation unit, and a ring II generation unit. By selecting the appropriate diffractive optical element and making necessary adjustments, this system can produce various illumination modes, such as single ring and double ring illumination modes. The intensity at the pupil plane, as well as the inner and outer diameters of the off-axis illumination mode, can be continuously adjusted.

Another notable patent is the "Method of indirect emission by nano-materials." This method involves providing an infrared up-conversion phosphor and a long-wave ultraviolet phosphor, treating their surfaces, and mixing them. The infrared up-conversion phosphor is excited by a near-infrared laser to emit blue light, which then excites the long-wave ultraviolet phosphor to emit visible light. This process allows for the convenient detection of biological reactions through the visible light emitted.
