چکیده
We present a maximum-likelihood method for parameter estimation in terahertz time-domain spectroscopy. derive the likelihood function parameterized frequency response function, given pair of waveforms with known time-dependent noise amplitudes. The provides estimates that are superior to other commonly-used methods, and reliable measure goodness fit. also develop simple model is by three dominant sources, their amplitudes terms set repeated waveform measurements. demonstrate applications material characterization.

Material parameter estimation with terahertz time-domain spectroscopy.
Imaging systems based on terahertz (THz) time-domain spectroscopy offer a range of unique modalities owing to the broad bandwidth, subpicosecond duration, and phase-sensitive detection of the THz pulses. Furthermore, the possibility exists for combining spectroscopic characterization or identification with imaging because the radiation is broadband in nature. To achieve this, we require novel m...
متن کاملMaximum Likelihood Parameter Estimation
The problem of estimating the parameters for continuous-time partially observed systems is discussed. New exact lters for obtaining Maximum Likelihood (ML) parameter estimates via the Expectation Maximization algorithm are derived. The methodology exploits relations between incomplete and complete data likelihood and gradient of likelihood functions, which are derived using Girsanov's measure t...
متن کاملMaximum-Likelihood Circle-Parameter Estimation via Convolution
In this paper, we present an interpretation of the Maximum Likelihood Estimator (MLE) and the Delogne-Kåsa Estimator (DKE) for circle-parameter estimation via convolution. Under a certain model for theoretical images, this convolution is an exact description of the MLE. We use our convolution based MLE approach to find good starting estimates for the parameters of a circle, that is, the centre ...
متن کاملUncertainty in terahertz time-domain spectroscopy measurement
Measurements of optical constants at terahertz—or T-ray—frequencies have been performed extensively using terahertz time-domain spectroscopy (THz-TDS). Spectrometers, together with physical models explaining the interaction between a sample and T-ray radiation, are progressively being developed. Nevertheless, measurement errors in the optical constants, so far, have not been systematically anal...
متن کاملParameter Estimation via Gaussian Processes and Maximum Likelihood Estimation
Computer models usually have a variety of parameters that can (and need to) be tuned so that the model better reflects reality. This problem is called calibration and is an inverse problem. We assume that we have a set of observed responses to given inputs in a physical system and a computer model that depends on parameters that models the physical system being studied. It is often the case tha...
