“…The limb is illuminated with an eye safe laser and the back reflected secondary speckle patterns [18] are analyzed with a camera. The use of such a concept was already demonstrated for non-contact biomedical monitoring including different bio medical parameters such as heart rate [19], blood pulse pressure [20], remote estimation of alcohol in blood stream [21], non-invasive monitoring of glucose concentration in blood [22,23] and measurement of intra ocular pressure. In this paper we adjust the concept and perform experimental validation of the speckle based sensing technology to analyze the responsivity of the measuring setup to pressure waves and vibrations that are applied via loud speaker and from that to deduce the possibility of fractions or cracks in the bonds of the inspected organ.…”

“…We examined to what extent wrong selection of threshold value will reduce the performances as expressed through efficiency. Figure 11 presents the performances of the best and worst threshold value which are also compared to the greedy probabilistic algorithm (Shenhav et al, 2012). It is clear that that the best threshold has a clear advantage.…”

“…In previous works we were able to develop photonic sensor in order to measure human biomedical parameters (Zalevsky et al, 2009;Beiderman et al, 2010;Beiderman et al, 2011b;Cojoc et al, 2012;Beiderman et al, 2012;Shenhav et al, 2012;Margalit et al, 2014). Our previous measurements included heartbeat rate and shape (Zalevsky et al, 2009), blood pulse pressure (Beiderman et al, 2010), estimation for glucose concentration in the blood stream (Beiderman et al, 2011b), intra-ocular pressure (IOP) in the eye (Margalit et al, 2014), estimation of amount of alcohol in the blood stream (Shenhav et al, 2012) and even using our sensor as a tool for early detection of malaria infected red blood cells (Cojoc et al, 2012). For some of those parameters such glucose concentration and IOP the alternative is invasive or at least non pleasant procedure for the human patient.…”

“…Algunos cambios en la piel de las personas pueden indicar la presencia de graves enfermedades que necesitan tratamiento, se ha reportado que el tamaño de los poros de la piel es un indicador de una condición de salud de la persona. Algunos estudios han considerado que midiendo la dispersión de la luz sobre la piel, se puede detectar sustancias como el alcohol y la glucosa [15,16]. La penetración selectiva de ciertas longitudes de onda ópticas en la piel se puede caracterizar por la luz dispersada en función del tamaño de los poros de la piel.…”
