Wavelength diversity coupled with fiber-based time delay, optical energy delivery, and ultrasonic energy sensing, are proposed to form a novel, rapidly tunable (e.g., 1 Khz-100 Mhz) and wide instantaneous bandwidth (e.g., >50% bandwidth at center carrier), ultrasonic probe system for therapy, diagnostics, and non-invasive surgery, particularly for intracavity operation with a typical 100 channel/transducer element count. This ultrasonic system architecture is a multi-wavelength optical delay line module using two high speed (i.e.,time), bulk acousto-optic tunable filters, that provide collinear, high power, multi-wavelength optical input and output beams. This wavelength selection module also provides high optical throughput (e.g., 90% efficiency) and excellent (e.g., -30 db) optical blockage of the unwanted leakage (undiffracted) light, preventing noise propagation when such modules are cascaded to provide many variable signal time delays.
