Jet Propulsion Laboratory is developing a Europa Lander astrobiology mission concept to search for biosignatures within Europa’s subsurface. However, Europa’s rugged terrain presents a number of physical hazards for landing. MIT Lincoln Laboratory is designing a radiation-hardened real-time direct-detection LIDAR system at 532nm to aid with autonomous hazard avoidance and landing site selection for this Europa Lander concept. The detector for this system is a 2048x32 array of silicon Geiger-mode APDs and covers the required field-of-view in one dimension, removing the need for 2D stitching and enabling real-time data processing. Detector design, improvements for radiation tolerance and component characterization results are presented.
Wide-area temperature monitoring and fever screening to mitigate COVID-19 using a long-wave infrared digital pixel focal plane array camera scanning system and real-time temperature estimation processing is presented. The s ystem enables multi-pose temperature readings of more than 20 people simultaneously over a 90° horizontal x 30° vertical field-of-regard at a 1 Hz update rate and +/- 0.6°F accuracy. The system has been operational in the MIT LL lobby since April 2020.
