Technology
This technology allows a dual-functional optical probe that operates both as optical imager and multi-site stimulating probe. The working principle for this device is based on the optical reversibility in which the spatially resolved imaging or stimulation function is attained via mode division multiplexing in a light guide or waveguide structure. The probe consists of a light source array, an imaging pixel array, an optical mode multiplexer/demultiplexer, segmented waveguides, and multiple optical elements.
Problem Addressed
Optical imaging of body cavities and optical stimulation of biological tissues are often considered as two separate procedures. The endoscopy-based optical imaging requires endoscopes that are relatively large in size with a limited structural flexibility and a small field of view. Alternatively, the optical-fiber-based neuromodulation requires waveguide arrays to stimulate multiple spatial site. These arrays have similar challenges to endoscopes of increased size, mechanical rigidity, and limited invasiveness to biological tissues.
Advantages
- Multifunctional probe
- Minimally invasive
- Small probe size
- Wide field of view
- Multi-site stimulation
- Low optical loss
- The light source and the biological tissues are thermally isolated
