It calculates absolute optical path length difference with very high precision, even when the spectrometer samples are not spaced in the usual \u201cquadrature\u201d way. It has a resolution from 1\/1,000 to 1\/100,000 of a wavelength, which supports high-precision sensing of parameters like refractive index, which can be used for salinity and density.<\/p>\n","protected":false},"featured_media":0,"parent":0,"template":"","meta":{"_acf_changed":false},"assignees":[94],"countries":[95],"impact-area":[132,97,96],"inventor":[150,127,151],"patent-status":[98],"technology-area":[178],"use-case":[108,134,180,176,179],"class_list":["post-42659","technology","type-technology","status-publish","hentry","assignees-woods-hole-oceanographic-institution","countries-united-states-of-america","impact-area-ecosystem-protection","impact-area-ocean-discovery-tech","impact-area-research-innovation","inventor-jason-kapit","inventor-norman-farr","inventor-raymond-schmitt","patent-status-granted-patent","technology-area-optics-photonics","use-case-deep-sea-research-exploration","use-case-environmental-monitoring-general","use-case-industrial-inspection-maintenance","use-case-marine-data-collection-sensing","use-case-oceanographic-research"],"acf":[],"_links":{"self":[{"href":"https:\/\/oceanworks.whoi.edu\/innovation\/wp-json\/wp\/v2\/technology\/42659","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/oceanworks.whoi.edu\/innovation\/wp-json\/wp\/v2\/technology"}],"about":[{"href":"https:\/\/oceanworks.whoi.edu\/innovation\/wp-json\/wp\/v2\/types\/technology"}],"version-history":[{"count":5,"href":"https:\/\/oceanworks.whoi.edu\/innovation\/wp-json\/wp\/v2\/technology\/42659\/revisions"}],"predecessor-version":[{"id":42674,"href":"https:\/\/oceanworks.whoi.edu\/innovation\/wp-json\/wp\/v2\/technology\/42659\/revisions\/42674"}],"wp:attachment":[{"href":"https:\/\/oceanworks.whoi.edu\/innovation\/wp-json\/wp\/v2\/media?parent=42659"}],"wp:term":[{"taxonomy":"assignees","embeddable":true,"href":"https:\/\/oceanworks.whoi.edu\/innovation\/wp-json\/wp\/v2\/assignees?post=42659"},{"taxonomy":"countries","embeddable":true,"href":"https:\/\/oceanworks.whoi.edu\/innovation\/wp-json\/wp\/v2\/countries?post=42659"},{"taxonomy":"impact-area","embeddable":true,"href":"https:\/\/oceanworks.whoi.edu\/innovation\/wp-json\/wp\/v2\/impact-area?post=42659"},{"taxonomy":"inventor","embeddable":true,"href":"https:\/\/oceanworks.whoi.edu\/innovation\/wp-json\/wp\/v2\/inventor?post=42659"},{"taxonomy":"patent-status","embeddable":true,"href":"https:\/\/oceanworks.whoi.edu\/innovation\/wp-json\/wp\/v2\/patent-status?post=42659"},{"taxonomy":"technology-area","embeddable":true,"href":"https:\/\/oceanworks.whoi.edu\/innovation\/wp-json\/wp\/v2\/technology-area?post=42659"},{"taxonomy":"use-case","embeddable":true,"href":"https:\/\/oceanworks.whoi.edu\/innovation\/wp-json\/wp\/v2\/use-case?post=42659"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
