Sophisticated, multi functional, optical online sensor systems
Patent pending DE10251610, patent grant in China 200310104764, stationary, scanning control processes, devices and systems for fast moving webs, or other material sheets to detect very precise and reproduce their specified product properties during production. OPSS-1 OPRL-1 vision control systems are equipped with multiple IR, NIR, VIS monolithic spectral color sensors, precision line lasers, CCD image devices, DSP, ATMEL, INFINEON sensor internal controllers, firmware, high speed data link, scanning speeds from 20 up to 500mm per second, web widths up to 5,000mm, measuring gaps from 2.0 up to 5.0mm, optical inline detection of permeability, porosity, spectral transmission, opacity, extinction, particle absorption, porosities ranges from 80 up to 5,000 respective from 50 down to 3 Gurley, position control of micro perforation lines with 0.1mm accuracy, from 0.050 up to 200 microns pore diameter by up to 300 pores per cm. With real time data determining of certain parameters, optical transmission, spectral grades, porosity integrals, envelope curves, internal calculated measuring values. Thus direct with close loops and feedback to power electronics of fabrics treatment units. 

Micro perforation or other treatment system makes it possible to compensate any changes in web treatment parameters and their partial locations so that each jumbo roll as well single, twin or quad bobbin sets can be produced quantity and quality controlled without intermediate stops in order of ISO 9001/9002 certifications. 

Thus sophisticate, precise, liable, repeat accuracy, easy visualized, optical online measurement techniques archives perfect ways to control and convert pneumatic, fluid, gas, jet streams, static permeability, naturally porous grades, filtration levels, breathable or ventilation effects. Their conditions can be easily met by using optical transmission technology thanks to described processing in fully online stationary or scanning control units, extremely small pore dimensions, high fabric speeds up to 1,000 meters per minute by high repetition rates. 

That completely independent from base material properties as consistency, coloring, density, formation, pin holes, smoothness, stretching, shrinking, brightness, opacity, spectral property, gauging thickness weight, moisture content and other known influences. 

Optical online OPSS-1 porosity vision scanning control system permeability cluster control for electrostatic or laser micro perforation machines, multiple color sensor head, spectral intensity, DSP, FPGA, CCD, line, precise, laser, position, material finger print detection, VIS wave length, opacity, defects, inspection, image control, scanner systems, process software, line, camera, vision control, filter, tipping, cigarette, book, packaging, magazine, bible, wall, Kraft, paper, carton, coffee, tea, food, co-extrusion foils, films, agriculture, cement, domestic or other moving fabrics or web material.
