Method for optimizing inspection speed in low, and fluorescent light applications without sacrificing signal to noise ratio, resolution, or focus quality |
摘要 |
The method for optimizing inspection speed during optical inspection of parts in high, low and fluorescent light applications. There are described autofocus mechanisms and methods optimized for fluorescent and non-fluorescent applications that when combined with a high speed CCD camera and high numerical aperture (NA) optics, achieve superior signal to noise ratio, resolution, and inspection speed performance.
