A noninvasive pulse-tracking technique has been exploited to observe the time-resolved motion of an ultrashort light pulse within an integrated optical microresonator. We follow a pulse as it completes several round trips in the resonator, directly mapping the resonator modes in space and time. Our time-dependent and phase-sensitive measurement provides direct access to the angular group and ph...

We present applied examples of laser scanner survey and data processing using phase measuring system. Beside the time of flight principle, the phase measurement principle represents another technique for medium ranges laser survey. High speed of acquisition, very high data density and resolution open new application frontiers in cultural heritage, but poses challenging problems with regard to d...

In this article, Structured Laser Illumination Planar Imaging (SLIPI) is used in combination with the LIF/Mie ratio technique for extracting a reliable two-dimensional mapping of the droplets Sauter Mean Diameter (SMD). We show that even for the case of a fairly dilute spray, where single scattering events are in majority, the conventional LIF/Mie technique still remains largely affected by err...

This paper proves the existence and uniqueness of quadratic mean almost periodic mild so-lutions for a class of stochastic dierential equations in a real separable Hilbert space. Themain technique is based upon an appropriate composition theorem combined with the Banachcontraction mapping principle and an analytic semigroup of linear operators.  

This Letter demonstrates a measurement technique based on frequency-to-time mapping and coherent detection, which enables the complete (i.e., amplitude and phase) characterization of dynamically reconfigurable photonic filters. We apply this technique to a unit cell from a silicon CMOS-compatible photonic lattice filter that has a rapidly changing transfer function with an 8.33 ns update time, ...

We propose an iterative phase recovery framework to improve spectral mapping with an application to improving the performance of state-of-the-art speech enhancement systems using magnitude-based spectral mapping with deep neural networks (DNNs). We further propose to use an estimated time-frequency mask to reduce sign uncertainty in the overlap-add waveform reconstruction algorithm. In a series...

The search for discrete quantum phase-space quasiprobability distribution functions is a subject of continuous and growing interest in the literature [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 26, 27]. The possibility of representing quantum systems characterized by a finite-dimensional state space by such discrete quasidistributions lays the ground for interesting developments and fruitful applicatio...

Evaluation is a key task in design, and a major goal in computational design is to develop techniques for evaluating designs throughout the design process, starting as early in the process as possible. We describe a computational technique for evaluating design concepts early in conceptual phase of engineering design. Conceptual design in engineering is abstracted as a function to structure map...

We present a proof of principle for a new imaging technique combining leakage radiation microscopy with high-resolution interference microscopy. By using oil immersion optics it is demonstrated that amplitude and phase can be retrieved from optical fields, which are evanescent in air. This technique is illustratively applied for mapping a surface mode propagating onto a planar dielectric multil...

alumina nanomaterials were synthesized via a solution combustion technique using tris-(acetylacetonato) aluminum(iii) complex (1) and tris-(2-formylphenolate) aluminum(iii) complex (2) at 600, and 1000 °c for 3h. the obtained data showed that the procedure without using fuel resulted in a better phase and morphology. to investigate the phase formation, powder x-ray diffraction technique was use...
