The device builds upon a conventional prism spectrometer; however, an additional scattering medium is introduced to generate a wavelength-dependent speckle pattern on the detector array. Simultaneous use of the prism and the scattering medium allows for both improved resolution and wavelength range. The generated speckle pattern secures a significant improvement in the resolution (up to 100 folds) and dynamic range over a conventional prism spectrometer. With the proposed spectrometer, implemented using a CCD camera, we demonstrate up to 17-pm resolution at 855-nm central wavelength and 756.5-nm wavelength range revealing a dynamic range of similar to 44 500. The dynamic range could be further improved upon using a detector array having larger area and a scattering medium offering a nar-rower spectral correlation function. With further development, the proposed device could be useful in a variety of spectroscopy applications, such as deep imaging of retinal layers in optical coherence tomography.", "doi": "10.1109/LPT.2018.2879247", "has_grant": false, "journal": { "issue": "24", "pages": "2139-2142", "title": "IEEE PHOTONICS TECHNOLOGY LETTERS", "volume": "30" }, "license": { "id": "cc-by" }, "publication_date": "2018-01-01", "relations": { "version": [ { "count": 1, "index": 0, "is_last": true, "last_child": { "pid_type": "recid", "pid_value": "29747" }, "parent": { "pid_type": "recid", "pid_value": "29746" } } ] }, "resource_type": { "subtype": "article", "title": "Dergi makalesi", "type": "publication" }, "title": "A Speckle-Enhanced Prism Spectrometer With High Dynamic Range" }, "owners": [ 1 ], "revision": 1, "stats": { "downloads": 7.0, "unique_downloads": 7.0, "unique_views": 30.0, "version_downloads": 7.0, "version_unique_downloads": 7.0, "version_unique_views": 30.0, "version_views": 34.0, "version_volume": 1232.0, "views": 34.0, "volume": 1232.0 }, "updated": "2021-03-15T12:54:47.530589+00:00" }
