Photogrammetry Department Increases Effeciency with In-House Scanning
December 2005 - The Leica DSW700 (Digital Scanning Workstation) offers precision scanning of color or black and white aerial photography film, providing digitized image data to our digital photogrammetric workstations.
In order to achieve optimal results without correction, it is essential that the initial scanning process facilitate getting as true an image as possible.
The DSW700 features a new three color LED light source, to enable more consistent illumination, increasing the illuminated area to accommodate a larger sensor. The new design prevents dust and dirt accumulation during scanning. The direct LED light source also keeps the stage and optical path free from unwanted heat sources, ultimately leading to improved image quality.
When combined with the high-performance sensor, the three color LED light source reduces capture noise, produces faster capture time and improves tonal sensitivity. Precise CCD image geometry and low distortion optics provide an essentially distortion free image.
