Stent optical inspection system calibration and performance.
Implantable medical devices, such as stents, have to be inspected 100% so no defective ones are implanted into a human body. In this paper, a novel optical stent inspection system is presented. By the combination of a high numerical aperture microscope, a triple illumination system, a rotational stage, and a CMOS camera, unrolled sections of the outer and inner surfaces of the stent are obtaine...
متن کاملNew DUV Optical Wafer Inspection System
OVERVIEW: In the midst of the rapid acceleration in the advancement of technology nodes, there is a demand for improved performance of waferinspection systems, namely, greater sensitivity as device size moves toward higher integration and density, newer materials such as ArF resist, Cu wiring and low-k films, and higher throughput with 300-mm-diameter wafers. In response to these demands, Hitac...
متن کاملRapid Global Calibration Technology for Hybrid Visual Inspection System
Vision-based methods for product quality inspection are playing an increasingly important role in modern industries for their good performance and high efficiency. A hybrid visual inspection system, which consists of an industrial robot with a flexible sensor and several stationary sensors, has been widely applied in mass production, especially in automobile manufacturing. In this paper, a rapi...

Advances in computer technology have dramatically increased raytrace speeds in optical engineering software. Increases in raytrace speed have, in turn, led to new methods for evaluating optical system performance. Designers traditionally evaluate imaging system performance with spot diagrams, MTF plots, ray aberration plots, and distortion plots. These tools are invaluable for two reasons: 1) t...
