Abstract

The aim of this study was measuring and determination of the optical properties of olive maturity stages (Arbquina variety) using visible laser with 543.5 nm with power 4 mW. The obtained results were as follows: a) The  intensity reflection percentages 1.36, 1.0 and 0.51% or absorption percentages 98.64, 99 and 99.49% not accepted for stages 1,2 and 3 respectively. Also, reflection percentage of 0.42% or  absorption percentage of 99.58% for stage 5 was refused, b) The intensity reflection percentage 0.47% or the absorption percentage 99.53% was indicator to the best maturity index (2.65) of olive variety. This is considering optical properties instead of ideal maturity index to determine harvesting time., d) Stage 1 was high reflection intensity percentage or low absorption intensity percentage followed with high moisture content and low oil content percentages. Meanwhile, stage 5 with low reflection intensity percentage or high absorption intensity percentage was of low moisture content and high oil content percentages. So, the stage 4 was considered suitable for oil extracting, because of low moisture content 40.41 % and high oil content 19.22 %.   It was standard to identify olive maturity stages to get high oil percentage according to optical properties.
