Research on Leonid MAC:
Team lead of the Japanese delegation. Faintest meteor flux, dynamics and spectroscopy by High-Definition TV
Digital Video Camera with Image Intensifiers(HD-TV-II)
High sensitive HD TV observations of meteor showers make it possible to study meteors
of fainter magnitudes and at higher astrometric precission than with normal
intensified cameras. The large pixel format video-frame-rate images
enable high quality slit-less spectroscopic studies of meteors as well.
For the 2001 missions, we will be equipped with our own intensified HDTV cameras.
The cameras used in the 1998 and 1999 Leonid MAC missions
were developed by NHK (Nippon Housou Kyoukai, the
Japan Broadcasting Corporation). These cameras are composed of a large diameter image
intensifier along with a 1-inch 2M-pixel FIT CCD, which has a resolution of 1150 TV
lines (1920 x 1035 pixels) and a high signal to noise ratio of 50 dB. Normal NTSC video
has 640x480 pixels, 6.5 times less. Its image format of 20 mm by 35
mm makes it possible to use high quality lenses for 35mm reflex cameras.
Results todate include studies of meteor stream activity in the context of the
satellite impact hazard, in publications in GRL and spectroscopic studies of metal
atom emissions reported in Earth Moon and Planets (Vol 82-83,
special Leonid Storm Research issue). This work served as the Ph.D. thesis material for
Shinsuke Abe, then at NOAO in Tokyo, Japan.
The images below were taken during the 1999 Leonid MAC mission.
