Gas-sensitive holographic sensors
Holographic sensors are photonic layered structures contained in analyte sensitive lms that upon illumination produce monochromatic reflections (λ). The present work reports the fabrication of oxygen and ammonia sensors in Nafi on membranes and hydrocarbon and volatile organic compound sensors in …

Miniaturisation of pH Holographic Sensors for Nano-Bioreactors
… and inexpensive manner. In this thesis, a pH holographic sensor (holosensor) is miniaturised to 3.11 nL in volume and integrated into a PDMS-glass microfluidic chip for monitoring the growth of Lactobacillus casei Shirota. Although other established methods for monitoring cell cultures can be …

Holographic Point-of-Care Diagnostic Devices
… rapid fabrication, optimisation and testing of holographic sensors for the quantification of pH, organic solvents, metal cations, and glucose in solutions. The sensing mechanism was computationally modelled to optimise its optical characteristics and predict the readouts. A single pulse of a …

Imaging using volume holograms
… this end, we first develop the theory of volume holographic imaging and calculate the imaging properties of the field diffracted by a volume hologram for the special cases of coherent and incoherent monochromatic illumination. We concentrate on two simple imaging system configurations, viz. …

Distributed-effect modal domain optical fiber sensors for flexible structure control
Recently, a new class of sensors has emerged which have scalar outputs derived from distributed measurements over a significant gauge length; these sensors are known as distributed-effect sensors. The most familiar example of a distributed-effect sensor is the piezoelectric laminate PVDF film; …
