DrDAQ is a versatile instrument that connects to the USB port of any PC. Using the supplied PicoScope software it can be used as an oscilloscope, spectrum analyzer and signal generator.
The following examples are results that I have previously obtained using a deflection machine to provide the deflection at a constant rate. While the changes in the optical signal/voltage signal were monitored continuously by PicoLog. The results are shown in Figure 4.
The test was repeated several times to assess the repeatability of the optical fibre output. The results of the repeatability test are shown in Figure 5.
I have also performed a continuous loading and unloading test as a means of testing the responsiveness of the optical fibre as a beam deflection sensor. The results are very predictable and hence show that the sensor has the potential to be used a sensor for monitoring the deflection of beams.
