Periodic Reporting for period 1 - DIRECTS (Direct Temporal Synthesis of Terahertz Light Fields Enabling Novel Computational Imaging)
Período documentado: 2021-10-01 hasta 2023-03-31
Initial actions in Objective 1 (Fundamental framework) were related to "THz light-field theory and simulations". This included initial EM simulations of light-field macro-pixels in special EM solvers like Zemax and HFSS. Results were obtained on ray-propagation, imperfections due to optical aberrations, and on-chip antenna patterns.
Design trade-offs were the primary focus on in Objective 2 (System optimization). Optimization was done in terms of resolution limits, implementation loss, and number of pixels. Results were obtained on macro-pixel lens geometries by the use of hyper-hemispherical Si lens configurations.
Circuit design activities were started in Objective 3 (System implementation) with the primary focus on establishing a mixed-signal RF/THz design flow in IC design tools like ADS, Cadence and open design tools. Initial source and camera pixel designs were simulated for "Temporal THz Light-Field Generators" and "THz Light-Field Cameras". Actions were taken in the design of fast parallel video controllers in "THz Light-Field System Integration".
Actions in Objective 4 (Algorithms) included initial studies on the recursive synthesis of THz light-fields for the purpose of performing measurements.
Finally, the actions in the Project Management were mostly related to recruitment of qualified personnel, the coordination of the WP tasks, and the planning of publications and dissemination activities such an invited talk at the European Machine Vision Forum (EMVF), an invited talk at the Advances in Analog Circuit Design workshop (AACD), preparation of book chapters, and a Inspect-Europe journal article for machine vision and optical measuring technology in industrial applications.
