“…The simulation results corresponding to the same weight values are plotted in dashed. Second multiplier transfer approximation as a function of hyperbolic tangent output voltage is (10) Thus, neuron transfer equation is (11) Curves relative to (10) and (11) have been represented with dots in Fig. 14.…”

“…NN have become an effective solution to improve the robustness and the data processing of integrated sensors [13]- [16]. Multilayer perceptrons (MLPs) are notably used in the case of continuous data values classification, such as surface detection [10]. However, there is no system or procedure capable of discriminating a wide range of surface types.…”

“…Starting from mid-1980's, there has been a growing interest in SM-LD based sensors for ranging, velocimetry, particlesizing, displacement and vibrometry among others [10], [11], [12], [13], [14]. Inspired by the success of such measurements on solid objects, the use of Doppler effect in SM-LD schemes has been proposed and applied for blood flow measurement [15], [16].…”

“…Same behavior shall be observed when the LD is tilted from an initial position by a small angle ( Fig.1(C)). However, as explained in [6] due to the roughness of the surface, "the scattered fields from every point illuminated by the light beam add with markedly different phases, resulting in an interference pattern known as speckles".…”
