Refractive index distributed optical element and image sensor including the refractive index distributed optical element |
摘要 |
A refractive index distributed optical element having a refractive index varying within a plane, including a positive refractive index distributed portion having a positive refractive index varying within the plane and a negative refractive index distributed portion having a negative refractive index varying within the plane. The absolute values of the refractive indexes of the positive refractive index distributed portion and the negative refractive index distributed portion decrease toward a region between the positive refractive index distributed portion and the negative refractive index distributed portion.
