Sensors are perhaps the most important and integral components of our modern society.
With global warming and environmental pollution garnering ever-increasing attention, as …

This is a comprehensive, critical, and pedagogical review of volumetric emission
tomography for combustion processes. Many flames that are of interest to scientists and …

We report a new approach to flow field tomography that uses the Navier–Stokes and
advection–diffusion equations to regularize reconstructions. Tomography is increasingly …

This paper puts forward a method of using two wavelengths of near-infrared light to identify
the oil–gas-water mixed flow patterns. Propose a new method of multiple correlation …

Direct absorption spectroscopy measurement of the 4. 3 μ m CO 2 using interband cascade
laser with a high spectral resolution, provides theoretical feasibility to retrieve the spatial …

Background-oriented schlieren tomography (BOST) is effective for flow field measurement;
however, different from general computed tomography (CT), the BOST utilizes the deflection …

Tunable diode laser absorption spectroscopy (TDLAS) tomography is a well-established
combustion diagnostic technique for imaging 2-D cross-sectional distributions of critical flow …

Current Background-oriented schlieren tomography (BOST) methods rely primarily on
iterative algorithms for reconstruction. Before reconstruction, a weight projection matrix was …

Chemical species tomography (CST) has been deployed in a wide range of applications in
the last two decades for multi-dimensional measurement of gaseous flow fields. CST offers …

This paper demonstrates a new method for solving nonlinear tomographic problems,
