Special Issue "Laser Sensing and Imaging"
Deadline for manuscript submissions: closed (31 December 2012).

Sensing applications are of ever growing importance in very diverse fields. This trend is also illustrated by special conferences and symposia devoted to certain aspects of sensing. New laser sources, spectroscopic approaches and imaging techniques play an increasing role as they enable non-contact sensing without or with only minimum sample pretreatment and/or sample preparation. Furthermore, hyperspectral approaches and improved data retrieval techniques have a great impact on the development of such techniques.
This special issue on Laser Sensing and Imaging addresses the following topics, but is not limited to:
- Laser-based sensors for gases, liquids, and solids
- Spectroscopy from UV to THz range
- Laser sources (with emphasis on tunability): diode lasers, VCSELs and VECSELS, interband cascade lasers (ICLs), quantum cascade lasers (QCLs), lead salt diode lasers, fiber lasers, nonlinear optical sources (difference frequency generation (DFG), optical parametric oscillators (OPOs)), frequency combs, etc.
- Measurement principles: absorption, fluorescence, reflection, scattering, photoacoustic and photothermal, Raman, Coherent Anti-Stokes Raman (CARS), dispersion, microring resonators, microfluidics, lab-on-a-chip, etc.
- Imaging techniques for spatially and temporally resolved information, e.g., for stand-off detection of explosives
- Mathematical algorithms for multi-component spectral analysis
- Application areas such as air monitoring, combustion, waste water, industrial process monitoring, workplace safety, agriculture and food science, security (particularly explosive detection), biological, medical such as breath analysis, non-invasive glucose monitoring, drug detection, etc.
We solicit review articles and original research papers on systems with emphasis on laser-based devices; and applications of such systems in areas as mentioned above. New sensing concepts, which are especially suited for multi-component or multi-parameter monitoring, novel approaches which allow measuring or controlling of so far inaccessible parameters or new application areas of such systems are also welcome.
