Wavelength variation of the depth of penetration of near infrared radiation in 'Hass' avocado fruit
This study reports on the wavelength dependence of near infrared (NIR) radiation penetration depth into 'Hass' avocado fruit for both transmission and reflectance modes in the wavelength range from 12,820−4,000 cm−1 (780−2,500 nm). For transmission mode, depths of penetration less than 3 m...

| description | This study reports on the wavelength dependence of near infrared (NIR) radiation penetration depth into 'Hass' avocado fruit for both transmission and reflectance modes in the wavelength range from 12,820−4,000 cm−1 (780−2,500 nm). For transmission mode, depths of penetration less than 3 mm occurred in the 5,369 to 7,413 cm−1 (1,862−1,348 nm) range, while the maximum depth of penetration of approximately 12 mm occurred in the region 11,293 to 11,987 cm−1 (885−834 nm). Two other wavelength regions were identified with significant depth of penetration in transmission mode, one around 9,272 cm−1 (1,078 nm) and the second at approximately 7,899 cm−1 (1,265 nm) with approximately 10 and 4.5 mm penetration respectively. In reflectance mode, despite the difference in the optical paths sampled, qualitatively similar trends in wavelength dependence of the depth of penetration were observed, with a lower penetration depth of 3.3 mm occurring around 9,311 cm−1 (1,074 nm) and maximum depth of penetration of approximately 4.8 mm occurring in the 11,625 to 11,987 cm−1 (860−834 nm) region. |
