BIOMIMETIC COMPOUND EYE OPTICAL SENSOR AND MANUFACTURING METHOD OF THE SAME

摘要

PURPOSE: An insect eye-shaped photo sensor and a method for manufacturing the photo sensor are provided to detect the incident direction of light by planarily or three dimensional-partially copying the structure of insect eyes. CONSTITUTION: A photo sensor includes a substrate part(100) and an ommatidium part(200). The substrate is based on a material of a first refraction index with respect to light. The ommatidium part is formed on or inside the substrate part and is based on a material of a second refraction index which is different from the first refraction index. The ommatidium part includes a micro-lens(201), an optical waveguide(202), and a cone structure(203). The micro-lens copies the facet lens of the ommatidium part. The optical waveguide copies the rhabdom of the ommatidium part. The cone structure copies the cylindrical cone of ommatidia of an insect.
