Latest Patents

One of his latest inventions is a surface inspection tool, which is a laser-based inspection tool (LIT) designed for inspecting planar surfaces. This innovative tool can simultaneously inspect both planar surfaces of disks used in disk drives. In a preferred embodiment, the incident beam is directed onto the surface at an angle slightly offset from perpendicular, allowing the reflected beam to be physically separated from the incident beam. The reflected beam is then routed to a detector that converts the intensity of the reflected beam into an analog signal. This analog signal is sampled and digitized to generate pixel data stored in a buffer. Various analyses are performed on this data, including calculating a rate of change in the pixel data. If the rate of change exceeds a selected threshold, it indicates a possible defect in the data area of the disk.

Another embodiment of the surface inspection tool involves light reflected from the surface being routed through a telecentric lens to a detector. This detector converts the intensity of the reflected beam into an analog signal, which is then sampled and digitized to generate pixel data. A data acquisition system sequentially stores this pixel data in a buffer. A median filter and derivative analysis can be applied to detect deviations indicating defects. Additionally, an optional calibration system can periodically reflect the scanning beam back to a detector to form a reference signal for absolute reflectivity measurements.
