HyperSAS

HyperSAS. Measures L t ( L w + reflected L s ) and L s in a single discreet direction Direction and angle between L t and L s measurements can be varied Also measures E d R RS can be calculated as R RS =(L t - ρ L s )/E d where ρ can be estimated. ρ estimated as 0.28 in this case.

Presentation Transcript

  1. HyperSAS • Measures Lt (Lw + reflected Ls) and Ls in a single discreet direction • Direction and angle between Lt and Ls measurements can be varied • Also measures Ed • RRS can be calculated as RRS=(Lt-ρLs)/Edwhere ρ can be estimated. • ρ estimated as 0.28 in this case

  2. Seaweed in HyperSAS • Group 2 pulled seaweed in front of the HyperSAS to determine its effect on the measurement. • Intentional contamination showed a clear “red edge” reflectance • Group 1 thought it may have had seaweed contamination on one reading. • Little effect from accidental contamination in this case
