A telecentric lens is a special optical lens (often an objective lens or a camera lens) that has its entrance or exit pupil, or both, at infinity. The size of images produced by a telecentric lens is insensitive to either the distance between an object being imaged and the lens, or the distance between the image plane and the lens, or both, and ...
An example would be standing on a straight road, looking down the road, and noticing the road narrows as it goes off in the distance. Visual perception of perspective in real space, for instance in rooms, in settlements and in nature, is a result of several optical impressions and the interpretation by the visual system .
comparison of telecentric lenses: Image title: Comparison of a conventional lens (1), object-space telecentric lens (2), image-space telecentric lens (3) and bi-telecentric lens (4), assuming the images are in sufficient focus by CMG Lee. Width: 100%: Height: 100%
Secondly, it only applies to an object-space telecentric lens. Third, it loses the point of how a telecentric lens actually works. What makes a lens telecentric is not that all the rays are "about parallel" to the optical axis. The properties of a telecentric lens come specifically from the fact that the chief ray is parallel to the axis.
Brunswik's lens model is a conceptual framework for describing and studying how people make judgments. For example, a person judging the size of a distant object, physicians assessing the severity of disease, investors judging the quality of stocks, weather forecasters predicting tomorrow's weather and personnel officers rating job candidates all face similar tasks.
Similarly, the allowed range of angles on the output side of the lens can be filtered by putting an aperture at the front focal plane of the lens (or a lens group within the overall lens), and a sufficiently small aperture will make the lens image-space telecentric. This is important for DSLR cameras having CCD sensors. The pixels in these ...
A hypercentric or pericentric lens is a lens system where the entrance pupil is located in front of the lens, in the space where an object could be located. In a certain region, objects that are further away from the lens produce larger images than objects that are closer to the lens.
Good Continuation: the principle of good continuation makes sense of stimuli that overlap: when there is an intersection between two or more objects, people tend to perceive each as a single uninterrupted object. Common Fate: the principle of common fate groups stimuli together on the basis of their movement. When visual elements are seen ...
