Glossary

ACR™ 3

All the versions of the base assembly are equipped with the high-capacity ACR 
technology for the reconstruction of codes (ACR™ 3). The new, third generation of 
ACR™ improves the read and reconstruction capability in the case of damaged or 
heavily slanted barcodes significantly.

Resolution

The smallest sub-division of an element, which can be distinguished by a given reader 
or represented by an output device.

Deflection

The angular range across which the mirror can be adjusted in order to scan a surface 
to be read.

Barcode

A series of lines of varying width, which are separated by empty spaces and represent 
numeric or alphanumeric data in a machine readable form.  Basically, a barcode 
symbol consists of a quiet area zone at the start, a start character, data or contents 
characters, check digit (if used), stop character and a subsequent quiet area zone. 
Within this basic structure, all the readable symbologies use their own format. 

Barcode label

A label containing a barcode which can be attached to an article.

Baud rate

A unit for measuring the data transmission rate or the speed during the data 
exchange.

CDRH (Center for Devices and Radiological Health)

The Center for Devices and Radiological Health (an agency belonging to the 
American health authority FDA) is responsible for safety guidelines and radiation limit 
values of laser devices. VISOLUX devices meet the requirements stipulated by 
CDRH.

CD SQUARE™

CD SQUARE™ provides useful information pertaining to the label position and the 
form of the object, which were determined in the read phase of the barcode. This 
innovative technology indicates the area which contains the code and measures the 
distance of the code to the reader.
