The capacity to load bacteriophages into electrospun nanofibers of two representative biocompatible polymers has been evaluated, paying special attention the possibility preserving their antibacterial activity. Specifically, work involves following steps: (a) Evaluation effect applied electrical field on phage activity; (b) evaluation activity when a lyophilization process could be avoided by using water soluble (e.g., poly(ethylene glycol); (c) dissolution polymer requires an organic...
This paper presents a novel calibration method for solid-state LiDAR devices based on geometrical description of their scanning system, which has variable angular resolution. Determining this distortion across the entire Field-of-View system yields accurate and precise measurements enable it to be combined with other sensors. On one hand, model is formulated using well-known Snell's law intrinsic optical assembly whereas hand proposed describes scanned scenario an intuitive camera-like...
This paper focuses on exploring ways to improve the performance of LiDAR imagers through fog. One known weaknesses technology is lack tolerance adverse environmental conditions, such as presence fog, which hampers future development in several markets. Within this paper, a unit designed and constructed be able apply temporal polarimetric discrimination for detecting number signal photons received with detailed control its spatial distribution under co-polarized cross-polarized...
The ELT M1 Local Coherencer is a non-contact metrology system aimed to simultaneously measure the relative pistons on six sides of target segment with respect neighbouring ones (reference segments) an accuracy below 300nm in range ±250μm while it supported by Segment Manipulator hanging from Crane. For this purpose, equipped Sensing Modules integrating patented partially coherent light interferometer, absolute tip-tilt sensor, fine alignment orient normal reference and coarse detection...
The interest in LiDAR imaging systems has recently increased outdoor ground-based applications related to computer vision, fields like autonomous vehicles. However, for the complete settling of technology, there are still obstacles performance, being its use adverse weather conditions one most challenging. When working bad weather, data shown point clouds is unreliable and temporal behavior unknown. We have designed, constructed, tested a scanning-pulsed system with outstanding...
In recent times, there has been a surge of interest in LiDAR imaging systems, particularly outdoor terrestrial applications associated with computer vision.
