Отрывок: To determine a confidence in- terval of the temperature T1D we use a standard technique for non-linear regression described in [17]. For this, we plot S as a function of temperature around point T1D. A confidence interval is defined by taking S(T) = constant, where the constant is determined by S(T) = S(T0)[1+p/(n– p)×F(n, p, α)], where p is the number of parameters, n is the num...

Аннотация : | In this paper, we demonstrate that combining a laser heating (LH) system with a tandem acousto-optical tunable filter (TAOTF) allows us to measure the temperature distribution (TD) across a laser-heated microscopic specimen. Spectral image processing is based on one-dimensional (1D) non-linear least squares fitting of the Planck radiation function. It is applied for determining the temperature T at each point (x, y) of the specimen surface. It is shown that spectral image processing using the 1D non-linear least squares fitting allows measurement of the TD of the laser-heated microscopic specimen with higher precision and stability than those of the conventional linear least-squares fitting of the Wien approximation of Planck’s law. |
