“…Generally, the μ a values of kiwifruit tissue detected by the established integrating sphere system and the IAD method were comparable to those reported in other research (Zerbini et al, 2002;Qin and Lu, 2008). The μ a values of kiwifruit reported by Zerbini et al (2002) were 0.005-0.450 mm −1 in the range of 650-1000 nm based on the TRS technique.…”

“…In the past decade, investigations for measuring tissue absorption and scattering coefficients of agro-products became popular for the previously mentioned reasons. Much attention was paid to the optical properties of apples perhaps because of the universality of this crop (Cubeddu et al, 2001a;2001b;Zerbini et al, 2002;Qin and Lu, 2008;Vanoli et al, 2009;Lu et al, 2010;Rizzolo et al, 2010). Other fruits (peach (Cen et al, 2012), pear (Zerbini et al, 2002), plum (Qin and Lu, 2008), etc.)…”

“…In the studies by two groups, the method of time-resolved spectroscopy (TRS) was mostly used by the research group at CRA-IAA (Consiglio per la Ricerca e la Sperimentazione in Agricoltura, Unità di ricerca per i processi dell'industria agroalimentare) in Italy and the hyperspectral imaging-based spatially resolved (HISR) method was mostly used by the research group in ARS/USDA (Agricultural Research Service, United States Department of Agriculture) at East Lansing, Michigan, USA. Although rare, research about absorption and scattering properties of kiwifruit was carried out by the two groups (Zerbini et al, 2002;Qin and Lu, 2008). There were some reports on optical property measurements of fruits and vegetables based on single integrating sphere: Saeys et al (2008) used single integrating sphere measurements combined with IAD to estimate the optical properties of apple skin and flesh tissue in the 350-2200 nm range for three cultivars.…”

Abstract:For a quantitative understanding of light interaction with fruit tissue, it is critical to obtain two fundamental parameters: the absorption coefficient and the scattering coefficient of the tissue. This study was to investigate the optical properties of kiwifruit tissue at the wavelength of 632.8 nm. The total reflectance and total transmittance of kiwifruit tissue from three parts (including the flesh part, the seed part, and the seed-base part) were measured using a single integrating sphere system. Based on the measured spectral signals, the absorption coefficient μ a and the reduced scattering coefficient μ s ' of kiwifruit tissue were calculated using the inverse adding-doubling (IAD) method. Phantoms made from Intralipid 20% and India ink as well as a Biomimic solid phantom were used for system validation.The mean values of μ a and μ s ' of different parts of the kiwifruit were 0.031-0.308 mm −1 and 0.120-0.946 mm −1 , respectively. The results showed significant differences among the μ a and μ s ' of the three parts of the kiwifruit. The results of this study confirmed the importance of studying the optical properties for a quantitative understanding of light interaction with fruit tissue. Further investigation of fruit optical properties will be extended to a broader spectral region and different kinds of fruits.
