Title: Optoelectronic system using spatiochromatic triangulation
Inventor: COHEN-SABBAN JOSEPH
IPC: G01B11/25
Filed: 1997-11-06
Granted: 2009-01-27
Abstract: In accordance with the teachings of the present invention, an optoelectronic system (10) is provided for surface digitization of an object using spatiochro-matic triangulation. The optoelectronic system (10) includes an illuminating subsystem (12) for illuminat-ing a measuring space (30) that contains an object (16) to be measured, as well as a viewing subsystem (14) for collecting the light reflected by this object (16) and for generating a three-dimensional topogra-phy of the object (16) using in depth chromatic coding of the object. More specifically, relay optics (22) are used to image a polychromatic light source (20) onto a source slit (24) which in turn passes images from the slit image onto a dispersing element (26). The ob-ject to be measured is illuminated with a continuum of monochromatic images along a cutting plane (x, z) within the measuring space (30). A color coded (x, a) representation, generated by the intersection of the cutting plane (32) and the surface of the measured ob-ject (16), is imaged onto a viewing slit of an imaging spectrograph. A relay lens (50) is used for project-ing this image onto the viewing slit (42). A grayscale imaging array (46) located in the image plane of the spectrograph (40) registers the color coded represen-tation, and by using spectrophotometric analysis, an image processor (40) translates this representation into a plane section of the three-dimensional topography of the measured object (16).
