The Solmirus All Sky Infrared Visible Analyzer (ASIVA) is a multi-purpose visible and infrared sky imaging and analysis instrument designed to operate autonomously or as a component in an instrument cluster. Its utility ranges from astronomy and meteorology to military applications. Potential data products include the following:
Cloud/No Cloud Reporting
Cloud cover determination
Photometric Quality Assessment
Sky Opacity/Transmission determination
Visible and IR measurement correlation and integration
Water vapor and Ozone determination
Sky/Cloud temperature (brightness and color) measurements
All-Sky (180 degree field-of-view) maps and analysis
ASIVA’s System Architecture:
A block diagram of the ASIVA instrument and its primary functionality is shown below:
The heart of the instrument consists of the infrared and visible imaging subsystems. The infrared subsystem consists of a 324×256 uncooled microbolometer array sensitive to 8-14 micron radiation, a 180-degree (all sky) custom designed diamond coated lens, and an optional six-position filter wheel for use with 1-inch filters. Custom infrared filters can be cost prohibitive. We find that a good selection of affordable 1-inch filters can be found from optics manufacturer JDSU (www.jdsu.com) in their sample filter catalog. The visible subsystem consists of a 1280×1024 CMOS monochrome detector, a 180-degree off-the-shelf lens, and an optional six-position filter wheel for use with 1-inch filters. A 2048×1536 CMOS color detector is also available.
The brain of the ASIVA instrument is the embedded processor which communicates with and controls the imaging subsystems and other subsystems such as the hatch-motor, filter-wheels, temperature-meters, and weather-monitoring subsystems. Data (both raw and processed) is passed over a fiber optic link to the host computer where it can be archived and displayed. Operational control of the ASIVA instrument as well as additional image processing is done via the host computer. Operational control software with graphical user interface has been developed and is customizable to the customer’s needs. This operation and control architecture is illustrated in the following block diagram.
