  • SPECTROSCOPY AND SPECTRAL IMAGING METHODS AND APPARATUS
    Publication number: 20120091550
    Abstract: The invention pertains to a new type of standing wave filter in which the detector is located within the cavity, rather than outside the cavity and methods of manufacturing such a filter.

  • Polaradiometric pyrometer in which the parallel and perpendicular components of radiation reflected from an unpolarized light source are equalized with the thermal radiation emitted from a measured object to determine its true temperature
    Patent number: 5436443
    Abstract: A radiation pyrometer for measuring the true temperature of a body is provided by detecting and measuring thermal radiation from the body based on the principle that the effects of angular emission I.sub.1 and reflection I.sub.2 on the polarization states p and s of radiation are complementary such that upon detecting the combined partial polarization state componentsI.sub.p =I.sub.1p +I.sub.2pI.sub.s =I.sub.1s +I.sub.2sand adjusting the intensity of the variable radiation source of the reflected radiation I.sub.2 until the combined partial radiation components I.sub.p and I.sub.s are equal, the effects of emissivity as well as diffusivity of the surface of the body are eliminated, thus obviating the need for any post processing of brightness temperature data.
