1. A non-destructive composite material inspection apparatus, a surface layer of composite material including a plurality of fibers having a fiber direction and a plurality of toughened particles distributed on the surface layer, comprising:

  • a first light module generating a first light ray projecting to a inspection area of the composite material surface, wherein the first light ray is polarized in a polarization orientation; and

    a stereoscopic microcamera module capturing the reflection light from the inspection area and outputting an image;

    wherein when the polarization orientation and the fiber direction are parallel, the image is a bright field image for analyzing the fiber direction and toughened particle distribution whereas when the polarization orientation and the fiber direction are orthogonal, the image is a dark field image for analyzing the toughened particle distribution and predicting the toughness of the composite material.
