Radiometri

A device that measures the intensity of radiant energy, consisting of a partially evacuated glass bulb containing lightweight vertical vanes, each blackened on one side, suspended radially about a central vertical axis to permit their revolution about the axis as a result of incident radiation.

Translations in context of radiometri in italian-english from reverso context entrando nello strumento, il segnale dallantenna era suddiviso in tre segnali, per essere elaborato da radiometri.

Radiometri

Radiometri on vastaanotin, jolla mitataan antennin välittämä signaali ja erotetaan se taustakohinasta. Se on passiivinen laite eli mittaa esimerkiksi maanpinnan lähettämää sähkömagneettista säteilyä. Ensimmäisillä radiometreillä mitattiin kirkkaan valon säteilyn voimakkuutta.

  it links with two functions first is optical excitation which produces thermal waves within the sample and second is radiometric detection of the associated emission of heat radiance. The first scheme is used to monitor the narrowband amplitude and phase of the signal for the modulated signal.

  radiometry is a set of techniques for measuring electromagnetic radiation, including.

Radiometric dating, radioactive dating or radioisotope dating is a technique which is used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay.

Radiometry is the measurement of energy or power in electromagnetic radiation fields or light. The average output power is the most common radiometric measurement since many light sources, including cw lasers and leds, emit output power that is constant over time.

Radiometric units to photometric units first requires knowledge of the light source. If the source is specified as having a certain color temperature we can assume that its spectral radiance emittance is the same as a perfect black body radiator and use plancks law.
