Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current imaging techniques face challenges in achieving deep penetration and high-resolution imaging of biological tissues due to scattering and interference, particularly in complex media like the brain, where linearly polarized light shows minimal chiroptical response and limited transmission.
Innovation Solution
The use of Majorana photons, which are a combination of spin and orbital angular momentum (SAM and OAM) and exhibit radial or azimuthal polarization, are transmitted through biological tissues to enhance imaging by increasing transmission and maintaining coherence, utilizing their non-separable and entangled nature to improve imaging depth and resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If linearly polarized light is used for imaging biological tissues, then the imaging setup is simple, but the transmission depth is limited and chiroptical response is minimal
Solution Approach 1:
The patent changes the polarization state parameter from linear to circular, and introduces vector beam characteristics (radial/azimuthal polarization) to enhance light-tissue interaction. This parameter change enables deeper penetration and stronger chiroptical response in biological tissues while maintaining imaging capability
Solution Approach 2:
The patent employs composite light structures combining multiple polarization states (circular polarization with radial/azimuthal vector modes) to create Majorana photons. This composite approach leverages the advantages of different polarization types to achieve both deep tissue penetration and enhanced chiroptical imaging
2Device complexity
If conventional light sources are used, then the system is simpler, but the imaging depth and resolution are limited due to scattering
Solution Approach 1:
The patent utilizes wavelength parameter optimization by operating in the SWIR golden window (1600-1870 nm) where biological tissues exhibit minimal scattering and absorption. This wavelength selection dramatically improves imaging depth and resolution compared to conventional visible light sources
Solution Approach 2:
The patent introduces specialized optical components (q-plates, spiral phase plates, vector beam generators) as intermediaries to transform conventional light into Majorana photons with enhanced penetration and resolution capabilities while maintaining system feasibility
3Ease of operation
If standard polarization modes are used, then the implementation is straightforward, but the penetration depth in scattering media is limited
Solution Approach 1:
The patent changes the spatial distribution parameter of polarization from uniform (linear) to structured (radial/azimuthal vectors), creating vector beams that maintain polarization information through scattering events. This enables deeper penetration while preserving imaging quality
Solution Approach 2:
The patent adds the spatial mode dimension (OAM) to the traditional polarization dimension, creating a two-degree-of-freedom light structure. This dimensional enhancement allows the light to navigate scattering media more effectively and achieve greater penetration depth

AI summary
A super class of polarized transverse vector vortex photon beams patterns are mathematically represented here, which are Majorana-like among them are the radial and azimuthal Laguerre-Gaussian, hybrid π-vector beams, and Airy beams. These optical beams are consider spin-orbit coupled beams based on OAM and SAM parts of light. A Majorana photon is a photon that is identical to its anti-photon. It has within itself both chirality, right and left-handed twist in polarization (SAM) and wavefront (OAM). Applications using Majorana photons improve optical deeper imaging, higher resolution imaging, Nonlinear Optics effects (SHG, SRS, SC), optical communication in free space and fibers, quantum computer as basic qubit, and entanglement for security.
