In this paper, we used infrared light in the range of 8–12 μm to develop and test an optical imaging system to detect air bubbles flowing in oil. The system basically comprises a broadband light source and a 31 × 32 thermopile array to generate i

Fiber Bragg gratings are used to measure the flow in pipelines by means of the temperature evolution, at two different measurement points, after transit of a thermal slug. Results analyze both laminar of turbulent flow regimes.

We describe the optical and electrical characterization of a poly(p-phenylenevinylene) derivative: poly(2-dodecanoylsulfanyl-p-phenylenevinylene) (12COS-PPV). The electrical characterization was carried out on devices with the FTO\PEDOT:PSS\12COS-PPV

The feasibility of generating tomographic images of objects inside crude oil is investigated in this paper. Crude oil in the visible spectrum usually appears as black oil. Nevertheless, in the mid-infrared range, crude oil presents bands of high tran

Optical fiber sensors have now been studied and developed for over 25 years and as they are successfully transferred from research labs to the real world, standardization issues become very important and threaten to limit the growth of the entire ind

Two-phase flows are present in many processes in nature as well as in industrial activities such as exploration, production and transportation of oil and gas. In many cases, flow monitoring determines the efficiency and safety of processes and equipm

Whilst crude oil is completely opaque at the visible/NIR regions it shows some transparency at the IR above 4 micrometers. This allows obtaining images from inside the volume containing crude oil.
