The document discusses hyperspectral imaging technology and applications. It summarizes that VTT has developed a new MEMS-based hyperspectral camera that captures the visible and near-infrared spectrum between 500-1000 nm with high spectral resolution. Examples of applications discussed include chemical imaging, defense and security, skin cancer detection, precision agriculture, environmental monitoring, and forest classification.

Seeing pollution:
SO2, NO2
• Compliance of individual ships with
forthcoming emission regulations esp.
SO2.
• Environmental regulation creates a new market
• Benefit of non-compliance ≥ 10 k€ / day (Capesize,
current prices) total costs of compliance 4-6 bn
USD/y (NS-BS)
• Currently PSC inspections cover only some % of
vessels
• A cost-efficient way to increase coverage for SO2
compliance is needed
• This market will be global in the next 5-10 years.
