Multispectral and Hyperspectral Sensors
-
Multispectral Hyperspectral
Multispectral / Hyperspectral Comparison
A prism or grating is placed in front of sensor for separating different wavelengths
Patterned filter coatings form part of the sensor
Creates a hyperspectral data cube with narrower bands over a continuous range
Creates a dataset with narrow bands over discrete
frequency ranges
Has discrete spectral bands (typically < 20)
Has continuous spectral bands (typically 100s)
Used to discriminate features and patterns Used to identify and characterize materials
Higher resolution and relatively smaller dataset
Lower resolution and much larger dataset
-
Multispectral Sensors
Image Sensor - Silicon• Monolithic
• Compact design
• Different pixel sizes for P and B zones
• TDI design for increased sensitivity and throughput
• Special design & timing for low crosstalk
• Designed to withstand harsh environmental conditions
