Bandpass Filters for Earth Mapping Applications
Bandpass filters for Earth mapping applications are designed to transmit selected spectral bands or laser wavelengths while reducing unwanted out-of-band light and atmospheric scattering. In aerial, drone, and satellite observation platforms, these filters isolate specific returning signals to capture accurate topographical, agricultural, and environmental data.
Applications:
- Satellite-based Earth observation for isolating specific spectral bands to monitor climate changes, land use, and oceanography
- Aerial and drone-based LiDAR systems for isolating reflected laser pulses to capture topographical elevation models and terrain mapping
- Multispectral and hyperspectral imaging for assessing vegetation indices, such as NDVI, and monitoring agricultural health
