摘要：
This research proposes a comparison off-axis digital holographic technology for thickness uniformity inspection of transparent products. Compared to existing technologies, the comparison off-axis digital holographic method has advantages such as high depth resolution and large field of view. Also, the proposed method can measure the thickness differences between standard product and the ones produced by one shot imaging with tilt correction. Comparative analysis is used to demonstrate the effectiveness.
