In-Process DA Software from LaserLinc
May 30, 2010
LaserLinc Inc., Fairborn, OH, has added Fast Fourier Transform (FFT) and structural return loss (SRL) options to its Total Vu software used to provide in-process tolerance checking, trending, SPC, feedback control, and data logging. FFT lets you analyze periodic deviations in a measurement, such as the diameter of a wire or cable. By combining the FFT information with specifications for line speed, the software can identify likely causes of the measurement deviations, such as a faulty pulley. The SRL Spectrograph shows a graphical representation of the signal loss that occurs at various transmission frequencies over the length of a product. The SRL option lets you assess whether any portion of the cable is expected to show significant signal loss at one or more frequencies.
