Development of Multimodal Microscopic Imaging System Capable of Hyperspectral and Multi-Wavelength Time-Lapse Imaging...

Area of Science:

• Biomedical Imaging
• Microscopy
• Spectroscopy

Background:

• Conventional microscopy lacks spectral information, limiting detailed biological specimen characterization.
• Spectral imaging enhances microscopy by integrating spatial and spectral data for deeper analysis.

Purpose of the Study:

• To present a novel multimodal microscopic spectral imaging (MmSI) system.
• To enable comprehensive microscopic analysis through integrated spectral and temporal-spectral scanning.

Main Methods:

• Utilized a liquid crystal tunable filter (LCTF) for flexible spectral selection and high spatial resolution.
• Integrated transmission hyperspectral imaging (THSI) and fluorescence hyperspectral imaging (FHSI).
• Developed a custom graphical user interface for synchronizing LCTF and CCD camera for efficient data acquisition.

Main Results:

• Achieved quantitative accuracy through system calibration in spatial, spectral, and temporal domains.
• Demonstrated system linearity with respect to exposure time and emission intensity.
• Validated system effectiveness and reliability on model systems.

Conclusions:

• The MmSI system provides versatile and reliable microscopic spectral and temporal-spectral imaging.
• The system is well-suited for advanced biomedical research, especially for studying dynamic biological processes.
