The necessary and sufficient input for transparency distortion measurement in the TOPINS software package consists of two images: an image of the reference grid and an image of the reference grid as seen through the examined transparency. The user can choose between two modes of optical distortion measurement: automated or manual
Automated Distortion Measurement
Before each measurement, the user defines relevant standard(s) or uploads an existing standard from the database. Once a standard is set in the automated mode, in less than a minute TOPINS will indicate the location of even the smallest distortion on your transparency. A carefully selected color range will clearly show the level of distortion, where detected.
The user fully controls optical standard options, angle tolerance, the choice of one and/or more standards, elimination of horizontal/vertical distortion display, color scheme alternation, 3D distortion display.
Manual Distortion Measurement
Many years of quality inspectors’ experience have shown that sometimes is necessary to measure distortion only on some specific spots on a glass, quickly change a standard and then repeat the measurement…..
This is why TOPINS features also a “manual measurement option”. Once an area of potential distortion has been detected visually, the inspector can measure the distortion using a highly intuitive “angle ruler”, designed specifically for this purpose. The angle ruler remains compliant with the specified standard throughout the measurement process.
