Special Issue Information

Dear Colleagues,

We are inviting submissions to a Special Issue on the state of the art in spectroscopy and its core components.

With the rapid development of science and technology, spectral technology has played an increasingly important role in many important fields such as aerospace, astronomical telescope, interstellar exploration, national defense security, environmental protection, food safety, etc. Raman spectroscopy, fluorescence spectroscopy, infrared spectroscopy, laser spectroscopy, LIBS spectroscopy and other spectroscopic techniques have been widely used due to their unique technological advantages. The development of advanced spectral technology and core components such as gratings, detectors, and filters is a key factor in promoting the continuous progress of scientific research and production and has received the attention of scholars from different countries. In our humble opinion, the participation of leading scientists is important to guide the readers and new users towards a world in which new spectroscopy techniques are widely adopted. Spectrometer design and improvement, application of spectral technology, spectral data processing, and the development of core components for spectrometers are the scope of this Special Issue. We invite submissions to explore cutting-edge research and recent advances in the fields of spectroscopy and its core components. Both theoretical and experimental studies are welcome, as are comprehensive review and survey papers.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Underwater spectral detection plays an important role in the study of the underwater environment, ecology, oceanography, and environmental monitoring. A kind of underwater spectral radiometer that can observe the distribution of underwater spectral radiation bidirectionally has been developed. The flat-field concave holographic grating is used as the only optical component, the optical design parameters are optimized, and the system is miniaturized. The mechanism of stray light generation in the spectrometer is studied, and a method of suppressing stray light is proposed and simulated. The level of stray light in the system is suppressed to the order of 10−4, the signal-to-noise ratio of the system is improved, and the ability to detect weak light is enhanced. The wavelength calibration experiment was completed, and the experimental results show that the wavelength resolution of the underwater spectral radiometer is better than 3 nm. Finally, the quantitative relationship between spectral irradiance and digital output is obtained through radiation in the calibration of the system. Full article
