Development of Long-wavelength Infrared Camera for Planetary Exploration

Project: Research project

Project Details


The objective of this task is to accurately characterize the spectral and radiometric performance of an existing RVS 640x480 microbolometer sensor chip assembly (SCA) (Figure 7) from 3 to 100 m. The microbolometer dewar will be retrofitted with a 1.0 mm thick, 2.55 cm x 2.55 cm CVD diamond window to provide long wavelength transmission. This window will be produced by Element Six, Cambridge, MA and metalized on the rim for subsequent installation at RVS onto the microbolometer focal plane. This modified microbolometer will be integrated with the camera core electronics (Figure 8) to produce a single package that will be installed into an interferometric Nicolet Nexus 670 FTIR spectrometer at the ASU Emission Spectroscopy Laboratory (Figure 9). This spectrometer has an optional detector mounting position and a flip mirror to allow a second detector package to be installed. Data will be acquired of the well-calibrated blackbody targets that are part of the Emission Spectroscopy Lab [Christensen et al., 2000; Ruff et al., 1997; Christensen and Harrison, 1993]. The microbolometer FPA will be installed and aligned in the Nicolet spectrometer and the signal output from the microbolometer camera core electronics will be acquired using the built-in Figure 5.
