Heterodyne detection schemes are widely used to detect and analyse high-frequency signals, which are unmeasurable with conventional techniques. It is the general conception that the heterodyne ...

The Heterodyne spectroscopy laboratory is dedicated to the development of techniques and equipment for millimeter-wave and Terahertz (THz) heterodyne spectroscopy. The laboratory is equipped with ...

The Heterodyne Spectroscopy Group in the Department of Terahertz and Laser Spectroscopy works on the development of instruments and methods for high-resolution THz spectroscopy based on mm-wave ...

Most array based sensing instrument will need some form of flat field correction process applied to their output to guarantee a uniform response. This is predominantly true of spatial heterodyne ...

In this paper, a new deep UV Raman instrument (ODIN developed by ISI) is described which uses a solid-state laser and a spatial heterodyne spectrometer. The instrument overcomes the practical ...

In 1918, while serving in France, he developed the concept for the heterodyne receiver. The circuit mixes a locally generated signal with the received radio signal to create a third signal that ...
