Application of a single-board computer as a low-cost pulse generator

Abstract: A BeagleBone Black (BBB) single-board open-source computer was implemented as a low-cost fully programmable pulse generator. The pulse generator makes use of the BBB Programmable Real-Time Unit (PRU) subsystem to achieve a deterministic temporal resolution of 5 ns, an RMS jitter of 290 ps and a timebase stability on the order of 10 ppm. A python based software framework has also been developed to simplify the usage of the pulse generator.

“…The arrangement ensured that each of the two cameras could see the laser light corresponding to a particular polarization only. The timing was synchronized by programming the BBB (Beagel Bone Black) controller (Fedrizzi and Soria (2015)) which provided the platform to specify a user-selectable time-shift, ∆t, between the two PIV systems. Multi-grid cross-correlation algorithm proposed by Soria (1996) was used for the processing of images.…”

“…The 2C-2D µ-PIV experimental set-up consists of: (i ) a pulsed LED light source to illuminate the flow field, (ii ) a microscope objective with 40x magnification and the optical sub-systems (lens, mirror, etc.) to focus the nematode along with the flow tracer particles, (iii ) a digital 5 MPx sCMOS camera to acquire the single-exposed images, (iv ) a Beagle Bone Black programmable real-time controller [Fedrizzi and Soria, 2015] used to synchronised the sCMOS exposure with the pulsed LED light source and (v ) a fluid chamber. Figure 1 shows the schematic representation of the experimental set-up and the apparatus used, which was fixed on an optical table.…”

“…[15]) or BeableBone Black (e.g. [16]). In the field of seismology, Saraò et al [17] have developed a low-cost Arduino based seismometer for educational purposes, although the sampling rate of the recorded signals is not constant and the units of the amplitude are not calibrated.…”
