Advanced photonic solutions for high precision astronomical imaging

The sharply rising productivity of exoplanet searches over the past two decades has delivered profound statistical insights into the prevalence and diversity of worlds around other stars. The frontier for astronomers has now expanded into the new era of exoplanet characterisation. Major progress here will only be achieved with new instrumental advances. Most highly sought-after is the capability to separate the faint light from a planet from the glare of the host star. The direct detection of planetary photons will enable unique spatial and spectral studies, revealing intrinsic properties of atmospheres and surfaces. In this project, a prototype instrument GLINT South (Guided Light Interferometric Nulling Technology) was developed. It employs nulling interferometry in which the light from the host star is actively rejected though destructive interference. Such advanced control and processing of starlight is accomplished by way of photonic technology fabricated into integrated optical chips. A monochromatic null depth was measured in the laboratory consistent with 0 within an uncertainty of 10-3. The instrument was tested at the Anglo Australian Telescope, and a sample of infrared-bright stars were observed retrieving uniform disk diameters in close agreement to the literature values, despite the stellar diameters being beyond the telescopes formal di raction limit. Furthermore, an algorithm was created to optimise the design of integrated optics waveguides for pupil remapping chips leading to the design of a 4-input remapping chip which will signi cantly expand capabilities and deliver multi-channel nulling as well as complex visibility data. The photonic nulling devices, inscribed within miniature, robust and environmentally stable monolithic chips are a promising avenue to one of astronomy's grandest challenges of characterising the chemical and physical environments of exoplanets

IoT Applications Computing

The evolution of emerging and innovative technologies based on Industry 4.0 concepts are transforming society and industry into a fully digitized and networked globe. Sensing, communications, and computing embedded with ambient intelligence are at the heart of the Internet of Things (IoT), the Industrial Internet of Things (IIoT), and Industry 4.0 technologies with expanding applications in manufacturing, transportation, health, building automation, agriculture, and the environment. It is expected that the emerging technology clusters of ambient intelligence computing will not only transform modern industry but also advance societal health and wellness, as well as and make the environment more sustainable. This book uses an interdisciplinary approach to explain the complex issue of scientific and technological innovations largely based on intelligent computing
