.
at a height of several tens of centimeters above the scanned object. The scanning
head can be arranged according to the principle of a scanning ruler and scan by
"viewing" the document from one edge to the other. Also, the heads can be
equipped with matrices arranged according to the principle of the matrix of a
digital camera. Such devices perform scanning in one shutter opening, which
significantly speeds up the process.

which is designed to align the height of the pages of the scanned document.
Depending on the scanner model, the cradle can be equipped with a pressure
glass to smooth the surface of the document and reduce distortion during
scanning. For scanning books or stitched documents with a limited opening
angle, there are V-shaped book cradles. It is worth noting that some
manufacturers equip scanners with a V-shaped cradle with two scanning heads
arranged symmetrically and with such an inclination to the vertical axis that each
head scans only one page of the book.

advantages of the scanner

2
The scanner allows you to
obtain electronic images of
high-quality originals.
Advanced deep autofocus
technologies built into the
planetary scanner allow
digitizing originals with high
quality, regardless of their
thickness, format and degree
of dilapidation. The
contactless scanning method
avoids damage to the original
during digitization.
When scanning in black-andwhite mode, ELAR PlanSkan DBC
provides dynamic binarization of
the image with maximum
preservation of document details
and hardware compression of
output data, converting them into
the standard industrial TIFF G4
format. When scanning in
grayscale mode (256 grayscale) or
color mode, the ability to select
file saving formats is
implemented.

The scanning node and special
software allow you to quickly
create high-quality copies of
various originals with minimal
operator involvement. The
software supplied with the
scanner allows batch scanning
and image processing for further
use in document management
systems. The scanner can be used
as a copier - working directly with
a laser printer to directly print a
copy of the scanned document.

advantages and
disadvantages
+high quality of the final work.
+the possibility of damage to
the original is excluded.
+alignment of lines, edges.
+eliminating a limited angle in
books.
+simple actions when using.
+high speed of work (significant
saving of working time).

disadvantages
-the process is quite tedious;
-the device is quite difficult to
-find on the market;
-high price.

where the scanner
is used?
The main sphere of use is museums,
libraries, archival institutions.
Planetary scanners are distinguished by a
higher quality of the final work. The wide
functionality allows you to perform
operations of high complexity and get a
high-quality result. This type of scanners
is one of the most popular and in
demand among consumers.
