Theory of Operation
Basic Principle
The VIVID 910 uses LASER triangulation. The object is scanned by a plane of laser light coming from the Vivid's
source aperture. The plane of light is swept across the field of view by a mirror, rotated by a precise galvanometer.
This LASER light is reflected from the surface of the scanned object. Each scan line is observed by a single frame,
captured by the CCD camera. The contour of the surface is derived from the shape of the image of each reflected
scan line. The entire area is captured in 2.5 seconds (0.3 seconds in FAST mode), and the surface shape is
converted to a lattice of over 300,000 vertices (connected points). VIVID gives you more than a point cloud; a
polygonal-mesh is created with all connectivity information retained, thereby eliminating geometric ambiguities and
improving detail capture. A brilliant (24-bit) color image is captured at the same time by the same CCD. Unlike
other scanners, the VIVID has no parallax error, its "spot - on"!
High Accuracy Measurement
A high-accuracy scanner and a high-accuracy Calibration facility unit to be used for calculation of 3-D data have
been developed for the VIVID 910.
The 3-D reference chart traceable to the national standards has also been established to utilize the technology and
algorithm that enable higher accuracy measurement.

The manufacturing center of Konica Minolta Sensing
Inc. (Location: Aichi Pref., Japan) was approved by
the British certification organization Lloyd’s Register
Quality Assurance for certification under the ISO
9001: 1994 international quality management
system standards on March 3, 1995. Since its
establishment in 1990, the center has carried out the
development and production of precision
instruments and associated application software for
the measurement of color, light, and shape.
Certification was awarded to the center’s quality
management system, including design,
manufacturer, management of manufacture,
calibration and servicing.Certification was carried
over to the ISO 9001: 2000 standards in February,
2003.
