Bright field inspection
Webmicroscopy as dark-field. Its inspection rate was quite rapid at the time, equivalent to about 30 100-mm wph. Its minimum detectable dielectric particle diameter was about 3 µm. A large difference between the bright field and dark field approaches is that in the latter, one typically has a situation in which the average size of the detected ... Webcollected during defect inspection using bright-field microscopy. This volumetric approach allows conversion of focus-resolved 2-D collected images into 3-D volumes of intensity information and also permits the use of multi-dimensional processing and thresholding techniques to enhance defect detectability.

WebDefects such as scratches, dents, slivers, scale and holes are easily recognisable in this light. Bright Field lighting is generally used on dull or matte finished surfaces. If the surface is smooth and shiny, a very high percentage of the light will be reflected back at the operator creating `hot spots` that can make inspection difficult.
