- Illumination should be increased as the lens aperture is closed (i.e. higher f/#). High power lenses usually require more illumination, as smaller areas viewed reflect less light back into the lens. The camera's minimum sensitivity is also important in determining the minimum amount of light required in the system.
Using Structured Illumination | Edmund Optics

- Structured illumination utilizes specific patterns of light to determine the geometric shape and depth of objects. An effective 3D system can be constructed by illuminating objects with different patterns, such as grids, dots, or lines, while minimizing cost, components, and complexity. Since a well-calibrated system increases measurement accuracy, it is important to understand that …

- When choosing lighting for the application we are making a decision that will affect image contrast as much as any other single component. Obtaining this contrast in the image should be the primary concern at the onset of the project. Using this logic, we should choose the lighting at the beginning of the system-design process.

- Low-angled illumination. From the images, direct illumination is aimed towards the object directly with no angle, and high-angled illumination is aimed at an angle of around 60-degree parallel from the object. Both showcase very similar traits in terms of imaging, but with the high angle, the object receives a greater concentration of light resulting in more reflection than direct …
