Scanning diffractometer for the rapid analysis of microparticles and biological cells
A laser diffractometer is described which employs a novel scanned array of optical light guides to record the angular intensity variation of light scattered radially by a particle throughout an arc of 180° in approximately ...
Detection of a bright ridge in the 2.2 MU-M emission of M82
Photometric scans through the central region of M82 with a resolution of 6 arcsec reveal that the 2.2-micron emission source has a compact ridge structure which is approximately aligned + or - 10 deg with the major axis ...
Hatfield near-infrared polarimeter
The design of the Hatfield Polytechnic Observatory's near-infrared (IJHKLM) polarimeter is described and its performance iliustrated by some representative observations on bright standard stars. Preliminary measurements ...
