Abstract:
At present, people are using holographic technologies to shape complex optical beams for both fundamental research and practical applications. However, most of the reported works are focusing on the generation of a single beam pattern based on the computer-generated hologram (CGH). In this paper, we present a method for simultaneously shaping the multiple beam lattice where the intensity and phase of each individual beam can be prescribed along an arbitrary geometric curve. The CGH that is responsible for each individual beam is calculated by using the holographic beam shaping technique, after

Abstract:
Background: Electron-beam shaping opens up the possibility for novel imaging techniques in scanning (transmission) electron microscopy (S(T)EM). Phase-modulating thin-film devices (phase masks) made of amorphous silicon nitride are commonly used to generate a wide range of different beam shapes. An additional conductive layer on such a device is required to avoid charging under electron-beam irradiation, which induces unwanted scattering events. Results: Phase masks of conductive amorphous carbon (aC) were successfully fabricated with optical lithography and focused ion beam milling. Analysis

Abstract:
This thesis describes an electrically thin surface used for electromagnetic applications in the microwave regime. The surface is free-standing and its primary purpose is to modify the phase distribution, or the phase and amplitude distribution of electromagnetic fields propagating through it: it is called phase shifting surface (PSS) in the first case, and phase and amplitude shifting surface (PASS) in the second case. For practical applications, the surface typically comprises three or four layers of metallic patterns spaced by dielectric layers. The patterns of the metallic layers are design

Abstract:
Broadband spectral content is required to support ultrashort pulses. However this broadband content is subject to dispersion and hence the pulse duration of corresponding ultrashort pulses may be stretched accordingly. I used a commercially-available adaptive ultrashort pulse shaper featuring multiphoton intrapulse interference phase scan technology to characterise and compensate for the dispersion of the optical system in situ and conducted experimental and theoretical studies in various inter-linked topics relating to the light-matter interaction. Firstly, I examined the role of broadband ul

Les télécommunications laser en espace libre sont limitées en portée par la turbulence atmosphérique. L'optique adaptative, par la correction de la phase turbulente à l'émission du faisceau, a permis d'étendre leur domaine d'exploitation.Toutefois, sur de longues distances de propagation, cette correction n'est plus suffisante et il faut également précompenser l'amplitude du faisceau émis.

Abstract:
Advances in ultrasound technology are shaping the way we apply echocardiography today. The industry has now developed a vast array of scanners that are targeted to different clinical requirements, budgets, and applications. In general, they can be categorized into high-end, mid-range, portable, and handheld scanners. Aside from image quality, much emphasis is placed on ergonomics, the user interface, and the patient data archiving system, which are all important to optimize workflow. Phased array transducers are used in echocardiography. Much of the signal processing (i.e. beam forming) occurs within the transducer. Further developments in computer processing and transducer technology have also led to the development of three-dimensional (3D) matrix array probes. Other transducer types necessary for a fully functional echocardiography laboratory include the pencil probe (for continuous wave spectral Doppler recordings) and the transoesophageal probe, which now also permits live 3D transoesophageal echocardiography scanning. Many of the functionalities of modern scanners are ‘software based’, where packages for specific applications such as stress echocardiography, speckle tracking, or advanced 3D image analysis can be integrated into the systems.
