In this paper, we present the design, fabrication and testing of a new micro optical sensor probe with side-viewing function to enable in-field visible-near infrared diffuse reflectance spectroscopy (VNIR-DRS) for soil. The optical probe consists of two microfabricated source chips and two collection chips. The source chips are used to deliver oblique (45… CONTINUE READING
