The utility model relates to an object-space telecentric type chroma detecting lens which comprises a front lens set (1) and a rear lens set (2). The chroma detecting lens is characterized in that a diaphragm (3) is installed at the focus of the front lens set (1), and the input ...
object space. The light from the object is split by a beam splitter 420, e.g., a 50%/50% split mirror, which splits the light beam into an upper arm and a lower arm. Along a upper arm there is a first upper arm lens group 430 and a second upper arm lens group 440, which ...
JonathanCheung12,PhillipMaire12JinhoKim1JonathanSy1Samuel AndrewHires13 Highlights Summary Active tactile perception combines directed motion with sensory signals to generate mental representations of objects in space. Competing models exist for howmiceuse these signals to determine the precise location of ...
PURPOSE:To constitute a titled device so that it is not influenced by interference of a thin film, by placing a telecentric optical system, and illuminating partially coherently a face corresponding to a pupil of this optical system. CONSTITUTION:An object to be detected 10 passes through a diap...
, in an extreme case, the pupil surface possibly invades into the lens system. In such case, it is almost impossible to provide the mirror within such small space at an inclined angle. Considering this point, therefore, the lens used in this patented device may not be the telecentric lens...
the telecentric lens 20 is provided with a cylinder lens that effects refraction only in the vertical scanning plane, it being possible to use a toric lens that also provides a refraction effect in the horizontal scanning plane orthogonal to the vertical scanning plane and parallel to the optical...
A center of the aperture diaphragm is located at a front focus position of the Fourier transformation object lens so as to form an image-space telecentric optical path. An image sensor photosensitive surface is located on the rear focal plane of the Fourier transformation object lens, which is ...
First, the diamond is placed on a turntable, and a single CCD camera with one telecentric lens captures silhouette images from multiple views as the turntable rotates. Next, accurate closed contours are extracted from the silhouette images sequence, and a 3D model of the diamond can be ...
space, as well as having an optical relay system arranged optically behind each image section for imaging the respective image section on a respective separate detector line, wherein the total number of the optical relay systems is divided into at least two groups, each group being assigned to ...
Additionally or alternatively, the position of the object may imply at least one orientation information of the object, indicating an orientation of the object in space. The detector comprises: at least one optical sensor, the optical sensor being adapted to detect a light beam traveling from ...
