Certain insect body and wing surfaces interact with light in unique ways to reflect circularly polarized light or to produce colorful interference patterns. Our study characterizes these optical signatures with the goal of testing whether insects can perceive these optical signatures (i.e. have matched filters).
We proposed a simple noise model based on the photon transfer method for the testing of a hybrid optical sensor for imaging in short-wavelength infrared regime. The model and the proposed testing procedure allowed us to separate the noise sources; then work on noise mitigation.
The polarization of objects relevant to remote sensing imaged with midwave and longwave infrared passive polarimetric sensors is not intuitive due to the multiple variables influencing polarization. We analyze polarization for varying conditions and compare simulated data with measurements collected in laboratory and field experiments.
