Special Issue Information

Dear Colleagues,

Techniques for optical imaging, which is without either an image sensor or mechanical scanning, are attractive in various research fields such as biological imaging, terahertz imaging, spectroscopic imaging, and so on.

There are two main methods regarding these techniques. One is single pixel imaging or a single pixel camera. This method is based on compressive sensing and optical modulation with specific patterns.

The other is called computational ghost imaging. In this method, statistical characteristics of speckle phenomena are important to obtain two-dimensional structures of the target objects.

In these methods, there are many issues for practical use. We believe various research fields and technologies may benefit from computational ghost imaging and/or single pixel imaging. We expect, through our efforts, that this Special Issue will be able to publish many interesting results, ideas, proposals, and discussions related to these methods, which could provide breakthroughs and be helpful for practical applications.

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.

Computational ghost imaging (CGI) is one of several attractive techniques for optical measurement because it can determine two-dimensional structures of target objects without using an image sensor. However, conventional CGI is not suitable for practical use in terms of measurement time. In this paper, we report on reducing the optical measurement time in CGI and propose a new CGI implementation. The proposed method utilizes the wide bandwidth of laser diodes. We can obtain a set of speckle patterns required in computational ghost imaging in a significantly shorter time by changing emission patterns. Consequently, this method is suitable for high-speed measurements. The concept of the method is described and verified by numerical analysis. Further, optical setup for the experimental verification is assembled. As verified with experiments and signal processing, the proposed method can provide reconstructed images of targets.
