Abstract :
High resolution imaging of objects in the Terahertz region of the electromagnetic spectrum requires operating in the near field region. Correlative interferometric approaches based on mathematical expressions for near field measurements are developed for reconstructing images of 1-D extended objects. The approach relies on providing constrained least squares fit between computed autocorrelation from sensor measurements and the expression for the near field autocorrelation.
