Telecentric lenses are used for precision optical two-dimensional measurements, reproduction (e.g., photolithography), and other applications that are sensitive to the image magnification or the angle of incidence of light. The simplest way to make a lens telecentric is to put the aperture stop at one of the lens's focal points.
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.
Social psychology utilizes a wide range of specific theories for various kinds of social and cognitive phenomena. Here is a sampling of some of the more influential theories that can be found in this branch of psychology. Attribution theory – is concerned with the ways in which people explain (or attribute) the behaviour of others. The theory ...
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.
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.
Personal construct psychology (PCP) is a theory of personality developed by the American psychologist George Kelly in the 1950s. Kelly's fundamental view of personality was that people are like naive scientists who see the world through a particular lens, based on their uniquely organized systems of construction, which they use to anticipate ...
Orthographic projection (also orthogonal projection and analemma) [a] is a means of representing three-dimensional objects in two dimensions.Orthographic projection is a form of parallel projection in which all the projection lines are orthogonal to the projection plane, [2] resulting in every plane of the scene appearing in affine transformation on the viewing surface.
Depth is also shown by height on the image. Lines drawn along the axes are at 120° to one another. In all these cases, as with all axonometric and orthographic projections, such a camera would need a object-space telecentric lens, in order that projected lengths not change with distance from the camera.
