## Question

Do Roll-2-Roll sensors require programming or calibration?

## Short Answer

No. Zero code, zero calibration — operators set up the sensor directly via touchscreen or web interface in minutes.

## Detailed Answer

No. Roll-2-Roll® sensors require **zero code and zero calibration**.

Traditional line scan cameras need a vision engineer, custom software, and careful calibration procedures. Roll-2-Roll® sensors take a fundamentally different approach:

- No calibration — the 1:1 magnification of the fiber-optic array means what the sensor sees is exactly what is there. No geometric correction, no lens calibration tables, no distortion compensation.
- No programming — adaptive edge detection algorithms are built into the controller firmware. Operators configure detection parameters through the SCU5 or SCU6x touchscreen interface or the 1DC built-in web interface.
- No vision expertise — setup takes minutes. Select the measurement mode, set thresholds, and the sensor is ready to run.

This simplicity is what makes Roll-2-Roll® sensors practical for inspection applications like splice detection, flag detection, and surface defect monitoring — you get vision-like capabilities without the vision system learning curve.
