Abstract

This project aims to develop compact on-chip polarization sensitive detectors crucial for many advanced detection systems since polarimetry provides complex information that other techniques cannot give. Polarimetric capability will be added to imaging cameras by the development of an organic coating based on anisotropic nanostructured emissive materials providing potential breakthrough innovation for a number of scientific and industrial applications also motivated by the low-cost of this approach.
ISMAC-CNR will develop coatings for color-sensitive image detectors by preparing double layer films of organic polymers aligned one orthogonal to the other and able to convert the polarization components of the incoming light into different colors, then discriminated by the detection system. The evaluation of the optical anisotropy and emissive properties of the films will be performed directly on the substrates to be coupled to to the CMOS camera.

Goals

The main objective of the project is to add polarimetric capability to imaging cameras in the NUV/optical, providing simultaneous measurements of the two different polarization states of the light. This objective will be obtained by the development of an innovative coating based on nanostructured emissive materials sensitive to the polarization of the incident light. These materials are based on organic conjugated polymers possessing both high extinction coefficients and emission efficiencies in the UV-visible region, combined with their intrinsic anisotropy originating from the 1D molecular structure. A double layer film of two organic systems aligned one orthogonal to the other will be coupled to image detectors so that the two polarization components of the incoming light are converted into two different colors. The low-production cost, low complexity/mass and power budget, along with the versatility of this kind of approach, may have breakthrough innovation potential for a number of industrial, medical and scientific applications.
