    Abstract: A detection device having: a terahertz wave generation element; a terahertz wave detection element; a first transmission path arranged upon the terahertz wave generation element; a second transmission path arranged upon the terahertz wave detection element; and a sealed section arranged between the terahertz wave generation element and the terahertz wave detection element and separated from the first transmission path and the second transmission path, so as to surround the first transmission path and the second transmission path. A space between an emission surface in the first transmission path and an incident surface in the second transmission path is connected to a space between the first transmission path and the sealed section and to a space between the second transmission path and the sealed section.

    Abstract: An active heterodyne detection system comprises a continuously tuneable laser source (1) emitting infra-red radiation, means (8) to split the infra-red radiation into a first part and a second part, means (4) to provide a frequency shift between the first part and the second part, means (8, 9) to direct the first part of the infra-red radiation to a target (2), means (4) to provide the second part of the infra-red radiation as a local oscillator, means (8, 9) to collect a scattered component of the first part of the infra-red light from the target (2), and means (5) to mix the scattered component and the local oscillator and route them to a detector (3) for heterodyne detection over a continuous spectral range. A method of active heterodyne detection over a continuous spectral range is also disclosed.

    Abstract: An opto-mechanical switch produces different optical paths from two optical path sections out of a plurality of optical path sections that are oriented in different spatial directions. The switch has an optical component on which one end of each optical path section impinges, and which is adapted to be moved linearly in a direction of movement at right angles to the optical path sections between different switching positions, in which it selectively couples different optical path sections optically with each other. Further provided is a measuring system for the analysis of fluids, having such an opto-mechanical switch.
