  • Apparatus for feature detection
    Patent number: 7193697
    Abstract: An apparatus for feature detection of a test object includes at least one light source module and at least one image capturing unit. The light source module provides light to illuminate a test region of the test object, and includes a substrate, a set of light-emitting components, and a light-focusing unit. The light-emitting components are mounted on the substrate for emitting light in parallel directions that are generally transverse to the substrate. The light-focusing unit is to be disposed between the light-emitting components and the test object, receives the light emitted by the light-emitting components, and focuses the light on the test region of the test object. The image capturing unit captures an image of the test object at the test region.
