Reflectance-based Photonic Crystal Liquid Sensors Made of ALD TiO2

A promising concept for a photonic crystal sensor for liquid sensing applications is introduced. The two dimensional photonic crystals are fabricated using a recently developed Atomic layer deposition ARrays Defined by Etch-back technique (AARDE) to obtain large functional surfaces and dense pillar arrays. Photonic signals are collected by means...

Optical remote sensing of water quality parameters: Interpretation of reflectance spectra

Non-destructieve bepaling van gewaseigenschappen met behulp van multispectrale scanning

The spectral distribution of radiation reflected by crops in the visible light region and the near infrared contains information concerning crop structure and the optical properties of the leaves and the bounding soil. Non-destructive determination on remote distance of crop properties by means of the measured spectral distribution of reflected...
