Abstract: The disclosed technology can be implemented to provide a method for processing data including representing original data in form of a number array with one or more row elements and one or more column elements based on the original data, re-arranging elements of the number array based on properties of corresponding elements in the number array and properties of other elements of the number array to form a re-arranged number array, modifying values of elements of the re-arranged number array by superposing a product of an amplitude variable A and values of a function F selecting from an ensemble of functions, and re-arranging the elements of re-arranged number array with the modified values of elements to generate a modified number array. The amplitude variable A is computed to optimize a cost function associated with the amplitude variable A, the respective function F, and elements of the number array.

Abstract: Devices, systems and techniques are provided for adaptive transformation of wavefronts of optical waves or other electromagnetic waves to either correct the undesirable aberration or provide desirable wavefronts or aberrations for various applications, including imaging, sensing, signaling and other applications.

Abstract: Techniques, systems, and devices are disclosed for obtaining optical images of a targeted object or scene such as a person's organ or tissue based on a fiber bundle having imaging optical fibers and optical phase modulation for improved imaging quality without using an objective lens to receive light from a target. Among its applications is an endoscope that bears no lens at the distal end, which affords miniaturization and bendability, and that has adjustable focal distance.

Abstract: Non-invasive optical detection devices and techniques that use optically discriminative detection of returned probe light from a target by spatially separating the returned probe light from the deep tissue structure and the returned probe light from the skin surface and the shallow tissue structure based on different wave vector components to improve the optical detection sensitivity in detecting the returned probe light from the deep tissue structure with reduced optical interference by the returned probe light form the skin surface and the shallow tissue structure.

Abstract: Non-invasive glucose testing devices and testing methods without using a blood sample are disclosed and can be used for optically interrogating substances overlaid by turbid media based on wavefront manipulation by means of binary phase masking. Through altering the degree of mode conformity between the fields reaching the collection optics and the field distributions of the propagation modes of optical waveguides the disclosed method can be used to suppress the collection of short-range light originated near the collection optics while permitting unimpeded collection of light originated from sites substantially behind turbid media.

Abstract: This application describes designs, implementations, and techniques for controlling propagation mode or modes of light in a common optical path, which may include one or more waveguides, to sense a sample.
