The GSB-4E intelligent document inspection instrument uses a microprocessor to control the excitation light source and reception band selection of the instrument, combined with the SWGDOC document inspection software system to achieve automatic control and intelligent analysis of the GSB-4E. The SWGDOC document inspection software not only has conventional document inspection image processing functions, but also can obtain the characteristic curves of document inspection materials under different excitation and reception bands, realizing qualitative to quantitative analysis and automatic comparison of document inspection.

The GSB-4E intelligent document inspection instrument can pre store and select different inspection modes corresponding to various types of inspection materials, enabling ordinary operators to have expert level inspection technology. The DSP controlled autofocus camera system can operate the machine through the text detector button or SWGDOC software. The host integrates 14 excitation inspection light sources and 8 reception band selections and their combinations. All system parameters can be stored and displayed on the observed image.
