The Small Ice Detector is a cloud and aerosol particle probe sensitive to particles between 1 and 100 μm size. Forward scattering of a laser beam by the particle is detected by a 2D sensor (ICCD camera), and is analyzed to obtain the particle shape and size: the radial and azimuthal symmetry of the diffraction pattern is determined by the symmetry of the particle. The SID-3 is mounted in open-path geometry to minimize shattering.
