A series of low cost, light weight, mission-adaptable multispectral imaging spectrometers have been developed by PAR Government Systems Corporation (PGSC), utilizing mass-produced commercial off-the-shelf (COTS) components. The developed MANTIS sensors have been used to collect continuous multispectral data for mine counter measures (MCM) and intelligence, surveillance, and reconnaissance (ISR) applications aboard low cost manned aircraft platforms. Each MANTIS system images four spectral bands simultaneously. The four user-selectable spectral filters are inserted into an easily accessible filter cartridge supporting pre-flight filter selection. Data acquisition is accomplished by COTS frame grabbers installed in a Pentium based personal computer and all digitized data is written in real-time to a redundant array of independent disks (RAID). PGSC has also developed a graphical user interface providing control, display and recording options. The MANTIS approach and simple design lends itself to low-cost modifications and improvements.
