The measurement sensor was based on the use of thermochromic liquid crystal paint and nichrome wire as a heater element. This paper incorporates results of tests carried out on filter paper using the developed measuring system. The examined filter paper was used for primary air intake combustion engine filters. Holes, in the range 50 μm to 2.35 mm were made in the filter paper using an excimer laser and air flow through the filter paper was examined. The visual patterns of air flow are compared and presented herein.

However, the effect of quantisation noise present in the position feedback may become problematic in certain applications. A technique is presented for overcoming the undesirable effects of encoder quantisation, when the digital encoder signal is

In the experiment, an acoustic emission transducer was coupled to the sample to acquire acoustic emissions of laser–material interaction and an oscilloscope was used to record the signals. The patterned areas were examined

One hurdle was that the seed layer (e.g., copper), on which the photoresist was spun, was easily attacked or damaged in laser ablation of the photoresist. To overcome this drawback, an acoustic emission transducer (AET) was coupled to the X-Y stage of an excimer laser system to acquire surface acoustic waves (SAWs) arising from pulsed laser-material interaction. The characteristics of such a process could then be investigated by analysing this feedback signal. The sequences of acoustic emission signals were transformed to frequency domain by employing fast Fourier transformations (FFTs). Analysis of the frequency spectrum showed that there were few dominant frequencies correlating with the ablation process through one material to another. Specifically, the amplitude of the dominant frequency was a function of the number of pulses, where an abrupt change could ...
