BIOCHEMISTRY MATERIAL SENSING DEVICE AND DISK DEVICE USING THE LIGHT WAVEGUIDE

摘要

PURPOSE: A biochemistry material detecting device and a disk device for detecting a biochemistry material using an optical waveguide are provided to accurately detect biochemistry materials and density. CONSTITUTION: A biochemistry material detecting device using an optical waveguide comprises a biochemistry material detecting unit(100), a light receiving unit(200), and an operation unit. The biochemistry material detecting unit comprises a core unit(110) in which inclined lattice parts(111) are formed. The light receiving unit is formed so that optical spectrums reflected from the inclined lattice parts are projected. The operation unit calculates a rate of light intensity of the optical spectrums, and detects density of the biochemistry material.
