This showcases the camera's ability to operate reliably in challenging industrial environments and provide critical insights for infrastructure integrity.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between a multispectral and a hyperspectral camera?

A: A multispectral camera captures data in a few (typically 3-10) relatively broad spectral bands, chosen for specific applications. A hyperspectral camera, conversely, captures data in hundreds of very narrow, contiguous spectral bands, providing a continuous spectral curve for each pixel. While hyperspectral offers more detail, multispectral is often sufficient and more cost-effective for targeted applications.

Q: How do I choose the right spectral bands for my application?

A: The selection of spectral bands depends heavily on the materials or phenomena you wish to observe. Our technical team works with clients to identify optimal bands based on the known spectral signatures of target materials or by conducting preliminary spectral analysis of samples. For instance, Red Edge and NIR are crucial for vegetation analysis, while specific visible bands might be critical for detecting certain color variations or contaminants.
