SURF: Announcements of Opportunity
Below are Announcements of Opportunity posted by Caltech faculty and JPL technical staff for the SURF program. Each AO indicates whether or not it is open to non-Caltech students. If an AO is NOT open to non-Caltech students, please DO NOT contact the mentor. Announcements of Opportunity are posted as they are received. Please check back regularly for new AO submissions!
Remember: This is just one way that you can go about identifying a suitable project and/or mentor. Click here for more tips on finding a mentor. Announcements for external summer programs are listed here.
*Students applying for JPL projects should complete a SURF@JPL application instead of a "regular" SURF application.
*Students pursuing opportunities at JPL must be U.S. citizens or U.S. permanent residents.

Background: |
We developed photoacoustic tomography (PAT) to peer deep into biological tissue. PAT offers in vivo functional, metabolic, molecular, and histologic imaging across scales from organelles to entire organisms. Additionally, we developed light-speed compressed ultrafast photography (CUP) to record 219 trillion frames per second, vastly surpassing commercially available camera technologies. CUP can capture real-time images of the fastest phenomena in nature, such as light propagation, and can be slowed down to record slower events like neural conduction. We are also exploring quantum entanglement for imaging. PAT physically combines optical and ultrasonic waves. Conventional high-resolution optical imaging of scattering tissue is limited to depths within the optical diffusion limit (~1 mm). PAT overcomes this limit, providing centimeter-scale deep penetration with high ultrasonic resolution and high optical contrast by sensing molecules. Its broad applications include early cancer detection and brain imaging. The annual conference on PAT has become the largest in SPIE’s 20,000-attendee Photonics West since 2010. CUP, with a single exposure, can image transient events occurring on time scales down to tens of femtoseconds. Like traditional photography, CUP is receive-only, avoiding the need for specialized active illumination required by other single-shot ultrafast imagers. CUP can be coupled with front optics ranging from microscopes to telescopes, enabling widespread applications in both fundamental and applied sciences, from biology to cosmophysics. Quantum imaging with the Heisenberg scaling improves spatial resolution linearly with the number of quanta, surpassing the square-root improvement of the standard quantum scaling. |
