WebbThree wavelengths of λ 1 = 1540 nm, λ 2 = 1550 nm, and λ 3 = 1560 nm were coupled to the input waveguides 1, 2, and 3, respectively. By measuring output optical power from the waveguides 4 and 5 for different wavelengths at different applied bias voltages, insertion loss, crosstalk, and extinction ratio of the device were calculated. Webb9 juni 2014 · If you take a look at the spectral reflectance curve of the Rapideye imagery (Figure 3) that correspond to the sample points in Figure 1, it quickly becomes clear which bands are which. Based on the comparison of theoretical Figure 2 and empirical Figure 3: Blue is band 1, green is band 2, red is band 3, Red edge is band 4 and NIR is band 5. WebbIn 1984, the IEEE microwave nerds agreed on the standard letter-band designations shown in the table below, the first two columns of which you should commit to memory … total terminals
