The Prototype Hyspiri-TIR (PHyTIR) instrument was developed under NASA’s instrument incubator program and is now operational in the laboratory. The scan head uses state-of-the-art focal plane technology to rapidly acquire data from an eight inch telescope focused at infinite, reflective relay and continuously rotating scan mirror. A series of narrowband interference filters are placed in close proximity to the focal plane. Arrays of 256×16 Mercury Cadmium detectors are under each filter. The detectors have their long wave cutoff at 13.2μm. The filters serve to block out unwanted radiation from other spectral channels, hence forming a high performance multi-band imager with the use of the scanning mirror.
