Design of a configurable multispectral imaging system based on an AOTF
Summary
This study introduces a configurable multispectral imaging system using an acousto-optic tunable filter (AOTF). The system captures a tunable spectral range, demonstrating good performance up to 50 nm bandwidth.
Area of Science:
- Optics and Photonics

- Spectroscopy
Background:
- Acousto-optic tunable filters (AOTFs) traditionally isolate single wavelengths.
- Configurable spectral imaging offers advantages over fixed-filter systems.
- Direct digital synthesizers enable advanced control of AOTF frequency sweeping.
Discussion:
- The developed system utilizes a direct digital synthesizer for versatile frequency control of the AOTF.
- This configuration allows for the capture of a configurable spectral range, moving beyond single-wavelength filtering.
- The system's performance was evaluated for its spectral and imaging response.
Key Insights:
- A novel configurable multispectral imaging system based on AOTF technology is presented.
