About This Webinar
The capabilities of multispectral filter arrays for Earth observation activities from space have changed significantly in the past 40 years. These capabilities have expanded from an initial offering of two to three bands in the visible range to now including over 100 separate bands covering a spectral range from as low as 280 nm up to 15 µm. Harrison discusses the historical progression, the current technology (monolithic and assembled), and future advancements.
