Abstract:
Abstract. Photogrammetry and Laser-Scanning are usually considered as complementary. Integration of these two observation methods has the potential to blend their individual advantages. The resulting benefit is likely to be higher in drone airborne mapping, which payload capacity (and thus the quality of the embedded IMU) is limited. Thus, the trajectory computed by the IMU is subject to important time-dependent errors: even if the global attitude is less adequate, it is self-coherent locally. For this reason, we propose a close integration of Photogrammetry with Laser-Scanning based on the co

We present time-resolved scanning x-ray microscopy measurements with picosecond photo-excitation via a tailored infrared pump laser at a scanning transmission x-ray microscope.

Controlling the heat load on the sample via additional reflector and heatsink layers allows us to conduct destruction-free measurements at a repetition rate of 50 MHz.

Mesoporous LaFeO3 as a visible light-driven photocatalyst was prepared by a nanocasting method using mesoporous silica (SBA-15) as a hard template. The as-prepared LaFeO3 photocatalyst was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), N2 adsorption-desorption, X-ray photoelectron spectroscopy (XPS), and optical absorption spectra. The characterization studies and experimental results showed that LaFeO3 with porous structure caused by the removal of SBA-15 hard template could enhance the specific surface area of the resulti

Abstract:
To achieve automatic photo capture of fundus images in an ultra-wide-angle laser-focused fundus scanning system, a pupil detection and positioning algorithm based on confocal laser technology was proposed and deployed. First, image preprocessing methods such as automatic laser intensity enhancement and contrast adjustment were applied to reduce the impact of noise and interference on subsequent processing. Next, the pupil was quickly and accurately located using the proposed pupil detection and positioning algorithm based on confocal laser technology. Finally, the movement information was calc

Abstract:
Photo-assisted Ultrafast Scanning Electron Microscopy (USEM) maps the dynamics of surface photovoltages and local electric fields in semiconducting samples. Photovoltages and their gradients close to surface affect the emission yield and the detection efficiency of secondary electrons (SE), leading to photoexcited SE 2D patterns. In this work, we present a method to characterize the evolution of the patterns up to ultrafast regime. These results reveal the role of surface states in affecting the external field dynamics at picoseconds. Moreover, we show that tiny changes in surface preparation

Zinc, nickel and silver oxide were prepared by the method of pulsed ablation laser in liquid, with different preparation conditions, where the number of pulses was changed (25, 50 and 75) and the frequency was 1 Hz and the energy was 600 mJ and at room temperature. We have used UV-visible spectroscopy, field emission scanning electron microscopy (FSEM), the EDX system, then these materials were added to the local dye and the photo-catalytic activity was applied to them using a UV-500 lamp for different periods of time (0, 30, 60 and 120 mint) and they acted as photo-catalysts.

In this study the effect of trimethylopropane triacrylate (TMPTA) content as a crosslinking agent on curing properties of UV-cured pressure sensitive adhesives (PSAs) was investigated. The curing properties were studied using gel fraction determination, photo-differential scanning calorimetry (photo-DSC) and Fourier transform infraredattenuated total reflection (FTIR-ATR) spectroscopy. Gel fraction sharply increased after expose to UV irradiation and increased with increasing TMPTA content. Moreover, the addition of TMPTA as crosslinking agent induced an earlier onset of auto acceleration and

Abstract:
This study focuses on the thermal stability of polyamide 6 with lignin, which is a flame retardant. In this study, we used the electrospinning method to produce nano-filament and to analyse the thermal stability of these filaments. The higher the voltage, the more difficult it will be to produce a bead-free spinning. This is done by varying the electric field and observing the presence or absence of "beads" on the non-woven. Figure 2 shows a SEM photo of polyamide 6 nano-filaments for the voltage value 14kV, the photo obtained corresponds to a spinning under 14 kV. It can also be seen that dec

The doping of B did not make any significant change on the morphology of ZnO nano rods as confirmed by scanning electron microscopy (SEM) without considerable change on periodic arrangement of nanostructures. The existence of B, Zn, and O is shown by ene
