Special Issue Information
Dear Colleagues,
The development of astronomy is always linked with advanced optical instruments. The electromagnetic spectrum observed by astronomical telescopes provides us the leading information sources to understand the universe. Astronomers first used visible light to study the universe, then expanded to non-visible light such as radio waves, infrared rays, X-rays, ultraviolet rays, and gamma-rays. The exciting thing is that gravitational waves are utilized to conduct research on the growth of the universe and the evolution of celestial bodies, which is far from being an extension of the electromagnetic spectrum.
All of the deployed and on-going observatories require continuous improvements in terms of large and precision optical surface fabrication and advanced telescope system development. There are still many challenges in advanced optics and sensing technologies for telescopes, such as insights on the relationship between the science objectives and the telescope requirements, novel optical design methods for telescopes, sensors for telescope control system, accurate optical surface testing, optical coating for the particular application, active and adaptive optics technology, and stray light suppression to reduce cost and engineering risk. Therefore, the current state of the pivotal technologies and effective solutions to the presented challenges for telescope system are the key areas of this Special Issue.
The areas of interest include, but are not limited to, the following:
- Designs of modern large optical telescopes;
- Telescopes for gravitational wave detection;
- Aspherical and freeform mirrors for high-resolution telescopes;
- High-energy optical/IR/FIR detectors;
- Wavefront sensing and wavefront control;
- Active and adaptive optics and laser guide star facility;
- Advanced manufacture technology for large-aperture telescopes;
- Control systems and structural, mechanical, and thermal engineering;
- High-resolution spectrometer for telescopes.

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. Sensors 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 2600 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.
