In this study, a new methodology for optical probe calibration has been proposed, which has been successfully validated with the Computed Tomography (CT) experimentation. The experiments were carried out in a cylindrical spouted bed with 2 mm diameter glass beads. The obtained calibration equation ...
The sample used for calibration, alignment, and PSF measurement is depicted in Fig. 1. The sample is composed of silica beads with an average diameter of 505 nm (<2% poly- dispersity index (PDI), where PDI is the standard deviation over the average diameter) that are assembled into a ...
We present a new method to calibrate a quadrant photodiode used as position detector to monitor latex beads trapped in optical tweezers. The method combines the dragging Stoke’s force with the thermal noise analysis (power spectral density (PSD)) of the Brownian motion of the trapped bead. Po...
The beads can be suspended in the aqueous media for a period of time due to a phenomenon known as Brownian motion, a random movement of small particles suspended in a liquid or gas medium caused by collisions of the particles with molecules of the medium....

The efficacy of the technique is demonstrated for diverse sparse dispersions, including dots, glass beads and spray droplets. The simple optical configuration and semi-autonomous calibration procedure make the method readily deployable and accessible, with a scope of applicability across vast research ...
Also, measurement of certain optical parameters is recommended to improve the confidence in the data obtained with the FSSP. Methods for making these measurements are given in detail.Calibration of the FSSP is described using three methods: glass beads, a droplet generator, and a rotating pinhole ...
need to be (manually) removed before reflection imaging. As high reflection intensities can damage the PMT (especially in the case of the high-power STED laser), we used low laser powers for reflection imaging and slowly increased the PMT gain until a signal from the gold beads was detected...
