Difference between a spectroradiometer and multispectral sensor

[المشرف العام]

Let's take as an example of a spectroradiometer MODIS, and as an example of a multispectral sensor the Landsat8 (OLI).What is the difference between these two sensors?

Should we compare a spectroradiometer instead with a hyperspectral sensor since in the case of MODIS the number of bands is more important (36 bands).

Thanks.
