Multi-Mode Fiber Microscopy and Sensing

We are using adaptive optics to control the field distribution at the input of a multimode fiber, allowing a focused spot of light to be formed in the three-dimensional space near the fiber output. We are exploring several applications, including: scanning microscopy (e.g., for minimally invasive endoscopy), targeted light delivery (e.g., for optogenetics), and sensor multiplexing.
