Abstract
We introduce transparent TOBE CMUT arrays for multimodal optical camera imaging, ultrasound imaging and photoacoustic imaging. We used an adhesive wafer bonding process technique to fabricate the 128-element lambda-pitch transducers and achieve high transparency ranging from visible to near-infrared with ultrasound center frequencies of 7.5-9 MHz. The arrays are anticipated to have utility for endoscopic, intravascular, and intra-operative probes for multimodal interventional guidance.
