Glossary of Machine Vision - T

T

• Telecentric lens. Compound lens with an unusual property concerning its geometry of image-forming rays. In machine vision systems telecentric lenses are usually employed in order to achieve dimensional and geometric invariance of images within a range of different distances from the lens and across the whole field of view.
• Telephoto lens. Lens whose focal length is significantly longer than the focal length of a normal lens.
• Thermography. Its is thermal imaging, a type of Infrared imaging.
• TIFF. Tagged Image File Format (abbreviated TIFF) is a file format for mainly storing images, including photographs and line art.
