Low temperature Electron-beam-induced current (EBIC) characterization of 3rd gen IR detectors
Offer N°: SL-DRT-15-0605
The optronic departement of LETI (DOPT) is a key laboratory in the field of high performance quantum IR imaging. We work in close collaboration with Sofradir, today a world leader manufacturer of high performance IR focal plane arrays. The increasing complexity of those IR retina (megapixel formats, ultra-fine pixel pitches, multicolor detection, and high operating temperature) calls for new advanced characterization methods.
Indirect X-ray photon counting imager for color medical radiology
Offer N°: SL-DRT-15-0614
As part of its activities in medical imaging, Leti has developed over several years several detectors technology, in order to propose new performance in X-ray imaging for different applications like radiology and X-ray CT scanner, gamma-camera, and for non-destructive testing. The first prototypes have shown a great interest in improving the image quality and dose reduction.
Adequate approximate computing for high energy-efficiency in Internet of Things applications
Offer N°: SL-DRT-15-0320
Approximate and inexact computing are non-conventional paradigms that allow bounded errors in calculation to obtain significant benefits in energy, performance, or circuit area . The thesis will bring these paradigms one step further, to adequately-approximate computing, by investigating dynamic accuracy adaptation. The candidate will propose methods to control hardware inexactness in software, in order to just meet the accuracy demands of applications, under strong energy constraints.
Space, time and frequency diversity for accurate range and angle of arrival measurement in UWB
Offer N°: SL-DRT-15-0008
The objective of the PhD is to explore the use of a 2-4 antennas subsystem with an Ultra-Wide-Band (UWB) RF front-end to bring angle of arrival estimation. The research aims to analyze by models the impact of the propagation, the antennas and the RF path imperfections on the estimation, to establish performance bounds and to propose architectural solutions and algorithms.
