Linear, Circular, Elliptical Polarized Light Detector and Emitter Based on Sub-Wavelength Wire and Wire Grid
Invention:
This invention introduces a technology for detecting and generating polarized light. The polarization state of the light can be linear, circular, or elliptical. The polarized light detector enhances image clarity by revealing hidden signals and improving the quality of both color and monochromatic images, especially in environments with low contrast and a high level of unpolarized light. This technology is beneficial in various fields such as industrial metrology, surveillance, remote sensing, microscopy, and medical imaging. Additionally, the invention includes a method for generating polarized light, which is useful in creating 3D displays using orthogonal polarized light to present stereoscopic images. It also aids optical metrology by providing a polarized light source for illumination. This dual capability makes it a versatile tool for improving imaging and measurement accuracy in multiple applications.
Background:
Polarized light detection has applications such as industrial metrology, surveillance, remote sensing, microscopy, and medical imaging, where image contrast is low and there is a significant presence of unpolarized light. Current solutions often struggle with accurately distinguishing signals from the background noise, leading to poor image clarity and limited effectiveness. This invention offers a more effective solution by enhancing signal detection and image clarity through advanced polarization techniques. This dual-detector approach ensures that all incoming unpolarized light is detected, enhancing the efficiency compared to traditional systems that lose about half the light in the detection process. It is compact, efficient, and can be easily integrated into various systems, making it a superior alternative to current technologies.
