Spectral Calibration For Multispectral Sensors
overall review score: 4.2
⭐⭐⭐⭐⭐
score is between 0 and 5
Spectral calibration for multispectral sensors involves the process of accurately adjusting and validating the sensor's spectral response to ensure precise measurement of light across multiple wavelength bands. This calibration is essential for applications like remote sensing, environmental monitoring, agriculture, and defense, where accurate spectral data underpins analysis and decision-making. The process typically includes laboratory calibration, onboard or in-field validation, and ongoing adjustment to account for sensor aging or environmental influences.
