Dissolved oxygen sensing using an optical fibre long period grating coated with hemoglobin [PDF]

open access: yes, 2016
A long period grating fiber optic sensor coated with hemoglobin is used to detect dissolved oxygen. The sensitivity of this sensor to the ratio of dissolved carbon dioxide to dissolved oxygen is demonstrated via the conversion of carboxyhemoglobin to

Fiber optic sensors [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1984
Over the past several years, many groups have been carrying out research in the area of fiber optic sensor technology, and many types of fiber sensors have been developed. Two of the most promising fiber optic sensor types will be discussed in this talk: phase-modulated single mode interferometric sensors and intensity modulated multimode fiber sensors.

Studies on Temperature and Strain Sensitivities of a Few-mode Critical Wavelength Fiber Optic Sensor [PDF]

open access: yes, 2018
This paper studied the relationship between the temperature/strain wavelength sensitivity of a fiber optic in-line Mach-Zehnder Interferometer (MZI) sensor and the wavelength separation of the measured wavelength to the critical wavelength (CWL) in a CWL-
