Figure 3. OLI edge response for the meter band. Spectral/Radiometry. Spectral and radiometric testing of the OLI was performed at BATC with the OLI in a thermal vacuum chamber and with the spectral and radiometric sources outside. Testing included in-band relative spectral response, linearity, stability, noise, and absolute calibration. Mar 21,  · LDCM sees eleven bands within the electromagnetic spectrum, the range of wavelengths of light. OLI collects light reflected from Earth's surface in nine of these bands. Wavelengths on the shorter side include the visible blue, green, and red bands. Wavelengths on the longer side include the near infrared and shortwave infrared. The OLI will instead use long detector arrays, with over 7, detectors per spectral band, aligned across its focal plane to view across the swath. This “push-broom” design results in a more sensitive instrument providing improved land surface information with fewer moving parts.

8 Operational Land Imager (OLI) was launched into orbit 11 February as the next generation of the Landsat Data Continuity Mission (LDCM). OLI collects. WebOLI provides two new spectral bands, one tailored especially for detecting cirrus clouds and the other for coastal zone observations. The OLI collects data for two new bands, a coastal/aerosol band (band 1) and a cirrus band (band 9), as well as the heritage Landsat multispectral bands. Additionally, the bandwidth has been refined for six of the heritage . OLI conducts measurements in the visible, near infrared, and short wave infrared bands of the spectrum. It is a push-broom sensor with a four-mirror. OLI will collect images using nine spectral bands in different of Earth's thermal energy obtained by LDCM's predecessors, Landsat 5 and Landsat 7. WebMar 11,  · OLI has nine spectral bands covering a spectral range from - nm, including five in the visible and near infrared spectrum (NVIR), three in the short-wave infrared spectrum (SWIR), and one panchromatic image (PAN) band for image sharpening. The thermal imaging band (TIR) was removed due to the extra cost of active cooling. Mar 21,  · LDCM sees eleven bands within the electromagnetic spectrum, the range of wavelengths of light. OLI collects light reflected from Earth's surface in nine of these bands. Wavelengths on the shorter side include the visible blue, green, and red bands.
