Taking advantage of the sparse reflection spectrum of the FBG array network, we have demonstrated the use of CS for compressing the spectrum at an excessively high compression factor up to 64. In addition to that, the spectral difference (SD) of the spectra is used to further enhance their sparsity for the CS model. In this investigation, four different configurations have been devised and tested to compare their performance and effectiveness. Configuration IV that is based on SD and deep neural network offers the best recovery performance. The proposed method is a potential tool for efficient data storage and transmission for FBG sensor network.<\/jats:p>","DOI":"10.1177\/01423312221149777","type":"journal-article","created":{"date-parts":[[2023,1,27]],"date-time":"2023-01-27T07:46:11Z","timestamp":1674805571000},"page":"1515-1524","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Efficient reconstruction scheme with deep neural network for highly compressive sensing of fiber Bragg grating spectrum"],"prefix":"10.1177","volume":"45","author":[{"given":"Yen-Jie","family":"Ee","sequence":"first","affiliation":[{"name":"Photonics Research Centre, University of Malaya, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0631-6682","authenticated-orcid":false,"given":"Kok-Sing","family":"Lim","sequence":"additional","affiliation":[{"name":"Photonics Research Centre, University of Malaya, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kok Soon","family":"Tey","sequence":"additional","affiliation":[{"name":"Faculty of Computer Science and Information Technology, University of Malaya, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hangting","family":"Yang","sequence":"additional","affiliation":[{"name":"Photonics Research Centre, University of Malaya, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cheong-Weng","family":"Ooi","sequence":"additional","affiliation":[{"name":"Photonics Research Centre, University of Malaya, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hangzhou","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Physics, Northwest University, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Harith","family":"Ahmad","sequence":"additional","affiliation":[{"name":"Photonics Research Centre, University of Malaya, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2023,1,27]]},"reference":[{"issue":"2","key":"bibr1-01423312221149777","first-page":"245","volume":"8","author":"Asmara RA","year":"2017","journal-title":"International Journal of Advanced Computer Science and Applications"},{"key":"bibr2-01423312221149777","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2015.2399864"},{"key":"bibr3-01423312221149777","doi-asserted-by":"publisher","DOI":"10.1109\/MSP.2007.4286571"},{"key":"bibr4-01423312221149777","doi-asserted-by":"publisher","DOI":"10.1109\/TIT.2010.2040894"},{"key":"bibr5-01423312221149777","doi-asserted-by":"publisher","DOI":"10.1016\/j.acha.2010.10.002"},{"key":"bibr6-01423312221149777","doi-asserted-by":"publisher","DOI":"10.1109\/ISWPC.2008.4556225"},{"key":"bibr7-01423312221149777","unstructured":"Chartrand R, Yin W (2008) Iteratively reweighted algorithms for compressive sensing.
