Solution Overview

Problem

Existing multimodal microscopic systems suffer from sequential or pseudo-parallel imaging, leading to increased processing times and reduced frame rates, and lack the ability to visualize processes with different modalities simultaneously, while also being expensive due to the use of costly optical switchers.

Innovation Solution

A multimodal microscopic system is designed with shared components across different modalities, utilizing a single electromagnetic wave source and flexible connecting lines, combined with beam combiners and splitters to enable simultaneous imaging and reduce the number of self-contained units, allowing for parallel processing of multiple modalities.
