Projects:
Dr. Sharma's research projects include:
-Scanning Lidar Imaging of Marine Aerosol and Water Vapor Fields (ONR-Environmental Optics) This coastal lidar is currently operating at Bellows Air Force Station ( for details see web page: http://imina.soest.hawaii.edu/lidar/). We are also developing a scanning water vapor differential absorption lidar(DIAL)system (partly supported by NASA) and an oceanic lidar (supported by NOAA/Sea Grant).
-Remote Raman system for Planetary Lander(NASA - PIID Program): In collaboration with Paul Lucey, we are developing a remote Raman system based on a small (5" dia) scanning telescope and a small pulsed laser that could be used for analyzing planetary rocks from a lander at a distance of 10-15 meter. The same system could also be used for analyzing gases and aerosols in planetary atmosphere.
-Petrologic Studies of Martian Carbonates in ALH84001 ((NSF- OPP) In collaboration with Ed Scott, we have examined with confocal micro-Raman system minerals in thin sections of Martian meteorites including ALH84001. Part of this work has appeared in Amer. Mineral. 84, 1569-1576 (1999).
-Structure and Properties of Explosives at High Temperature and Pressure (US DOE/ Los Alamos National Laboratory) In collaboration with scientists at Los Alamos National Laboratory, we are investigating structure and propertied of high explosive with a variety of techniques, including laser-induced fluorescence (LIF) depolarization, high P and T micro-Raman spectroscopy and confocal scanning laser microscopy (CSLM). A diamond 13c/12c isotope Raman pressure sensor has been developed for high-temperature / pressure diamond-anvil cells with aqueous and other chemically reactive samples ( for details see J. Applied Phys. 82, 3256-3265 (1997)).
