Results

Step 2 of a component-resolved dose calculation is the separation of the signal components in each individual measurement. Mathematically this process is called decomposition. The number of components \(K\) and their signal decay rates were determined in Step 1:

  • \(K=3\)
  • \(\lambda_1=1.6514\) \(s^{-1}\) (Fast)
  • \(\lambda_2=0.5231\) \(s^{-1}\) (Medium)
  • \(\lambda_3=0.0094\) \(s^{-1}\) (Slow2)

These parameters lead to the following CW-OSL model:

\[I(t) = n_1e^{-1.6514t}+n_2e^{-0.5231t}+n_3e^{-0.0094t} \]

The signal component intensities \(n_1\) to \(n_K\) were calculated for each of the 384 CW-OSL measurements. First, 3 signal bin intervals were defined. The value of each bin was set equal to the formula above, integrated over the bin interval. In consequence, each measurement was described by 3 equations with 3 unknown intensity values \(n\). These equations systems were solved by an algebraic approach, see section Methods for details.

Intensity over sequence

The behaviour of the signal component intensities in the course of measurement sequences contains information about irradiation and bleaching response and thermal- or photo-transfer effects of the associated defect states. Fig. 2 display the component intensity variations in the course of the measurement sequences. Just components which were bleached to at least 95 % during the analysed time window are displayed, to prevent scaling issues and data misinterpretation due to background correction issues.

Methods

Basics

The data analysis approach assumes that all CW-OSL signal curves in a data set can be sufficently described by a sum of exponential decays with first order kinetics:

\[I(t) = \sum_{i=1}^K n_ie^{-\lambda_it}\]

Here, \(I(t)\) is the CW-OSL signal, \(K\) is the number of signal components. Each component is defined by its intensity \(n\) and its decay rate \(\lambda\).

To achieve component-seperated dose information, the data analysis process is divided into multiple steps:

Step 2 workflow

The decompositon process in Step 2 calculates the signal component intensities \(n_1\) to \(n_K\) and their statistical errors \(\sigma\). An intensity value \(n\) is equal to the areas under the signal component curve, including the ongoing virtual signal beyond the stimulation end. The algorithm can be outlined as following:

Detailed explanations on step 2.1 and step 2.2 can be found in Mittelstraß (2019). Practical advice can be found in the R documentations ?optimise_OSLintervals and ?decompose_OSLcurve.

Signal bin intervals

In step 2.1, optimum signal bin intervals for the decomposition process are defined. optimise_OSLintervals() determines iteratively those integration intervals which asure the maximum mathematical independence between the signal components. This minimizes the impact of eventual systematic errors from the Step 1 data analysis. The optimise_OSLintervals() output depends just on the decay rates and the channel settings, not on the specific CW-OSL measurements.

Table 2: Time intervals for the signal bin integration \(I_{bin}=\int_{t_{start}}^{t_{end}}I(t)dt\). If the components decay rates were determined by a global average curve, the global average bin values are given by \(\overline{I}_{bin}\)

signal bin \(t_{start}\) \(t_{end}\) channels \(\overline{I}_{bin}\)
1 0.0 1.0 10 85485
2 1.0 5.6 46 41308
3 5.6 20.0 144 24181

Step 2.1 used the differential evolution approach of Price et al. (2006)), implemented by Ardia et al. (2020) in the function DEoptim from the package DEoptim.

Decomposition

In Step 2.2, the decomposition process is performed by decompose_OSLcurve() for each record saperately and can be summarized as following:

  1. Set value of each signal bin equal to the integrated basic equation. Obtain a system of \(K\) equations with just the component intensities \(n_1\) to \(n_K\) unknown.
  2. Solve equation system by Cramer’s rule and get \(n_1\) to \(n_K\).
  3. (Optional) Refine \(n_1\) to \(n_K\) by a Levenberg-Marquardt fitting performed by the function nlsLM from the package minpack.lm (Elzhov et al. 2016). This step enhances the result reliability in presence of an uncorrected signal background level but decreases the error estimation accuracy.
  4. Calculate the standard deviation for each signal bin by comparing the modelled CW-OSL curve with the actual measurement data.
  5. Apply the propagation of uncertainty for independent variables method onto Cramer’s rule and calculate the standard deviation \(\sigma_1\) to \(\sigma_K\) for each component intensity.

This approach (despite step 3) was first presented by Mittelstraß et al. (2014) and further developed by Mittelstraß (2019). An introduction in the mathematical concepts can be found for example in Bevington and Robinson (1992) or Bronštejn et al. (1989).

Error estimation

The intensity error values \(\sigma\) account just for statistical noise (e. g. shot noise and dark current noise). Other sources of error are not sufficiently accounted for. But they might be detectable through not-statistical scattering in the residual plot (lower plot in figure 1). Is the residual plot dominated by statistical noise, the CW.OSL model can be expected as valid. If not, one of the following systematic errors is likely:

  • Incorrect decay constants
  • Not-first-order decay kinetics
  • Insufficient number of signal components (under-fitting)
  • Unstable light stimulation
  • Inadequate or missing background correction

General remarks

This report was automatically generated by functions of the R package OSLdecomposition written and maintained by Dirk Mittelstraß (). This package is preferably used together with the R package Luminescence (link) by Kreutzer et al. (2012). For the dynamic creation of this HTML report, the R packages knitr and rmarkdown are used, see Xie (2015) and Xie et al. (2018). All diagrams are drawn with ggplot2 (Wickham 2016).

The data analysis method covered with this report was developed for CW-OSL SAR protocol measured quartz samples, see Murray and Wintle (2000). It might be also useful for the analysis of Al2O3 or feldspar samples measured with SAR-like protocols. You can use, share and publish this report and the containing results at will. But we demand to refer to the R package OSLdecomposition including its version number (21.2.15) if you publish the results in a peer-reviewed journal.
