Engineering Contradiction Analysis
1Measurement precision
If conventional imaging technologies are used to capture objects, then the imaging process is simple, but the ability to capture polarization information and determine object properties is insufficient
Solution Approach 1:
The imaging device is segmented into multiple specialized components: multiple polarized image sensors with different polarization orientations, a structured light source, and a processor. Each component performs a specific function in capturing and analyzing polarization information, enabling precise measurement of object properties through divided functional responsibilities
Solution Approach 2:
The invention adds the polarization dimension to conventional imaging by incorporating polarized image sensors that capture not only intensity but also polarization state information. This transforms the imaging process from capturing only spatial information to capturing spatial plus polarization information, enabling determination of material properties, surface orientation, and other characteristics that are invisible to conventional cameras
2Loss of information
If single perspective imaging is used, then the device structure is simple, but the depth information and feature extraction capability are limited
Solution Approach 1:
Multiple polarized image sensors capturing images from different perspectives are merged into a unified processing system. The processor integrates the image data from all sensors, combining polarization information and depth information to extract comprehensive object features, achieving complete information capture through combined data processing
Solution Approach 2:
The processor acts as an intermediary that receives image data from multiple polarized image sensors, performs complex computations to extract polarization and depth information, and generates the final feature extraction results. This intermediary component coordinates the multiple sensors and transforms raw data into meaningful information

Implementation Method 1
An object may produce polarized features that are related to the nature of the object when reflecting, diffracting, transmitting, refracting, and/or scattering an incoming light. Therefore, polarization information may be used to determine various properties of the object.
