Popping Microbubbles Help Focus Light Inside the Body

12-03-15

Changhuei Yang, Professor of Electrical Engineering, Bioengineering, and Medical Engineering, and his postdoctoral colleague Dr. Haowen Ruan have developed a novel technique called time-reversed ultrasound microbubble encoded (TRUME) that uses gas-filled microbubbles to focus light inside tissue. "Ultrasound and X-ray techniques can only detect cancer after it forms a mass," Yang says. "But with optical focusing, you could catch cancerous cells while they are undergoing biochemical changes but before they undergo morphological changes." [Caltech story]

Student Research in Biomedical Optics Wins First Place

07-02-15

Electrical Engineering postdoctoral scholar Dr. Haowen Ruan and graduate student Mooseok Jang, who work with Professor Changhuei Yang, have won first place for Best Student Poster Presentation at the Engineering Conferences International (ECI) series entitled “Advances in Optics in Biotechnology, Medicine and Surgery XIV.” Their winning poster demonstrated research in biomedical optics, specifically a novel technique that focuses light inside biological tissue by time-reversing the light encoded through popping of a microbubble. The technique has the potential to enable one to “see” through biological bodies with light.

Bending the Light with a Tiny Chip

03-10-14

Ali Hajimiri, Thomas G. Myers Professor of Electrical Engineering, and colleagues have developed a new light-bending silicon chip that acts as a lens-free projector--and could one day end up in your cell phone. They were able to bypass traditional optics by manipulating the coherence of light—a property that allows the researchers to "bend" the light waves on the surface of the chip without lenses or the use of any mechanical movement.

Pushing Microscopy Beyond Standard Limits

07-29-13

Changhuei Yang, Professor of Electrical Engineering and Bioengineering, and colleagues have shown how to make cost-effective, ultra-high-performance microscopes. The final images produced by their new system contain 100 times more information than those produced by conventional microscope platforms. And building upon a conventional microscope, their new system costs only about $200 to implement. This new method could have wide applications not only in digital pathology but also in everything from hematology to wafer inspection to forensic photography. [Caltech Release]
