Abstract: A method of acousto-optic imaging may include receiving a first signal from a first sub-aperture of a sensor array. The first sub-aperture may comprise one or more array elements of a first type. The method may further include receiving a second signal from a second sub-aperture of the sensor array. The second sub-aperture may comprise one or more array elements of a second type different from the first type. In some variations, the first type of array element may be an acoustic transducer (e.g., piezoelectric transducer) and/or the second type of array element may be an optical sensor (e.g., optical resonator such as a whispering gallery mode (WGM) resonator). The method may further include combining the first signal and the second signal to form a synthesized aperture for the sensor array.

Abstract: Sensing apparatuses and method of making the sensing apparatuses are disclosed herein. In some variations, a sensing apparatus can comprise at least one optical waveguide, and at least one whispering gallery mode (WGM) resonator configured to propagate a set of WGMs, where the WGM resonator communicates to the at least one optical waveguide a set of signals corresponding to the set of WGMs. In some variations, a polymer structure may encapsulate the at least one WGM resonator and/or the at least one optical waveguide. Furthermore, in some variations, the WGM resonator(s) may have one or more selectable modes with different bandwidth and sensitivity for sensing, which may, for example, enable tailoring the sensing apparatus to specific applications having certain bandwidth and/or sensitivity requirements.

Abstract: A system and method for compressed-sensing ultrafast photography for two-dimensional dynamic imaging is disclosed. The system and method may capture non-repetitive time-evolving events at up to about 100 billion frames per second. In an aspect, a digital micromirror device (DMD) may be added as the spatial encoding module. By using the DMD and applying the CUP reconstruction algorithm, a conventional 1D streak camera may be transformed to a 2D ultrafast imaging device. The resultant system may capture a single, non-repetitive event at up to 100 billion frames per second with appreciable sequence depths (up to about 350 frames per acquisition). In another aspect, a dichroic mirror may be used to separate signals into two color channels, and may further expand CUP's functionality into the realm of four-dimensional x, y, ?, t ultrafast imaging, maximizing the information content that may be simultaneously acquired from a single instrument.
