Special Issue Information
Dear Colleagues,
Spectral imaging, enabled by spectral cameras and optical sensors, merges the capabilities of digital imaging and spectroscopy by capturing the geometric image across multiple narrow spectral bands, expanding to cover visible, near-infrared, and shortwave infrared spectrums. This approach enables the detection of optical characteristics in objects that are typically unseen by traditional cameras or the human eye. These spectral attributes directly correspond to the chemical composition of an object, facilitating tasks such as object detection, identification, classification, segmentation, and enhanced color characterization. This sensing technology has emerged as a powerful tool across various fields including remote sensing, agriculture, biomedical imaging, and industrial inspection.
This Special Issue attempts to address recent advancements in spectral camera technologies, focusing on both hyperspectral and multispectral imaging systems. It covers key aspects such as spectral camera design, spectral imaging, spatial resolution, optical camera communication, and signal processing, along with their advantages and limitations. Related sensing applications and techniques of spectral cameras in various fields can also be covered in this Special Issue, emphasizing the significance of this technology in environmental monitoring, precision agriculture, medical diagnosis, material characterization, and joint communications and sensing.

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.
