Real-time Lock-in Software
Real-time lock-in thermography is an active measurement process for the non-destructive testing (NDT) of components. A heat pulse creates a sine-shaped temperaturetemperature
Measure of thermal energy density field in the component. Analysing the heat flow allows conclusions about various types of concealed defects to be drawn.
The module for real-time lock-in systems improves the signal-noise ratio especially for weak or low-contrast signals. This increases the detection rate and optimizes the measurement results. Data flow evaluation (lock-in correlation) for each individual pixel runs parallel to data recording and is displayed in the image in real time.
Users can freely define the duration of lock-in measurement in a range between 1 second and several hours. Our software also enables you to control and synchronize external excitation sources.
The advantages of the lock-in module:
- Improved signal/noise ratio and shorter integration times
- Parallel evaluation of the correlation of amplitude and phase position of each individual pixel
- Measurement periods from 1 second up to several hours
