Infrared Technology and Applications XXVII.
Standard GaAs/AlGaAs QWIPs are now well established for LWIR detection. The main advantage of this technology is the duality with the technology of commercial GaAs devices. The realization of large FPAs (up to 640 X 480) drawing on the standard III-V

Unmanned Systems Technology XXIII.
In this work a novel approach to collision avoidance radar is presented. Leveraging the chipsets currently in development for the automotive industry, with an operational band of 77 to 81 GHz a new frontend has been developed using a distributed freq

Observatory Operations: Strategies, Processes, and Systems VIII.
Identification of optical counterparts of gravitational waves (GWs) is one of the most exciting topics in astronomy. Since a typical sky map error region of the LIGO/Virgo is much larger than the field-of-view of optical telescopes, it is important t
