The Planck High Frequency Instrument (HFI) spectral response was determined through a series of ground based tests conducted with the HFI focal plane in a cryogenic environment prior to launch. The main goal of the spectral transmission tests was to measure the relative spectral response (including the level of out-of-band signal rejection) of all HFI detectors to a known source of electromagne...

Camouflage in marine environments requires matching all of the background optical properties: spectral, intensity and polarization components─ all of which can change dynamically in space and time. Current research suggests that polarization detection is more sensitive than other conventional detection methods in scattering media such as the ocean, hence underscoring the need to develop polariz...

By measuring the spectral reflection from the four different road conditions dry, wet, icy, and snowy asphalt, a method of classification for the different surfaces--using two and three wavelengths--is developed. The method is tested against measurements to ascertain the probability of wrong classification between the surfaces. From the angular spectral response, the fact that asphalt and snow ...

This paper presents a hierarchical deep framework called Spectral-Spatial Response (SSR) to jointly learn spectral and spatial features of Hyperspectral Images (HSIs) by iteratively abstracting neighboring regions. SSR forms a deep architecture and is able to learn discriminative spectral-spatial features of the input HSI at different scales. It includes several existing spectral-spatial-based ...

Measurements have been made of the relative photoileclric quantum eficiency ?(A) of SbCs3 cathodes of M ith Pyrex and quartz windows, from ~=200-650 mp. ?(A) depends on the window transinittame W(h), the cathode absorbance A(h, d) , the absolute photoelectric quantum efiiciency Qo(h) and the p/1otoelectron escape probability f (A, d). Comparison Irith other data has allowed the separation of th...
