    Abstract: The present invention comprises an approach for calibrating the sensitivity to polarization, optics degradation, spectral and stray light response functions of instruments on orbit. The concept is based on using an accurate ground-based laser system, Ground-to-Space Laser Calibration (GSLC), transmitting laser light to instrument on orbit during nighttime substantially clear-sky conditions. To minimize atmospheric contribution to the calibration uncertainty the calibration cycles should be performed in short time intervals, and all required measurements are designed to be relative. The calibration cycles involve ground operations with laser beam polarization and wavelength changes.

    Abstract: By employing a high-repeatability optical switch that transmits input optical power selectively either to the standard or the unit under test (UUT), OPHASE presents a system for performing a rapid, repeatable comparison between the standard and the UUT. Further, the selective routing of beam traveling through one of the two output fibers that are coupled to the switch either to the standard or the UUT enables the elimination of much of the system uncertainty by enabling initial characterization of the ratio, Rp, and inequivalence, Im, between the power outputs of the multiple output fibers coupled to the switch. This characterization is accomplished by using an angled interface which is constructed so as to allow simultaneous coupling of the multiple output fibers to the angled interface and enable the power readout of all the output fibers at the standard. Rp and Im are then used to calculate the correction factor that reduces the total uncertainty level in the subsequent calibration of the unit under test.

    Abstract: The invention relates to a sensor having a filter arrangement, downstream of which there is arranged a detector arrangement, and an evaluating device connected to the detector arrangement. The filter arrangement has at least a first filter, the suspect filter, and at least one second filter, the reference filter(s). The first filter is configured as a band pass filter allowing the passage of a first predetermined band, the suspect band. The at least one second filter is configured as a band pass filter allowing the passage of a second predetermined band(s), the reference band(s). The detector arrangement has at least one detector associated with at least one of the filters. The band passes reference filters are distributed above and below the band pass of the suspect filter. The sensor with advantage could be utilized within the IR band, and could advantageously be used to detect CO2.
