    Abstract: A method, non-transitory computer readable medium, and apparatus for calibrating a device using augmented data are disclosed. For example, the method measures k spectral values of each patch for a first plurality of patches generated by the device and a second plurality of patches generated by the reference device, creates a first augmented data set by selecting a delta (δ), wherein the first augmented data set comprises the δ applied k times to each one of the k spectral values of each one of the first plurality of patches, initializes initializing a function to create a second augmented data set for the reference device, solves the function to obtain a matrix of calibration values of the device that is based upon the first augmented data set and the second augmented data set and calibrates the device using the matrix of calibration values.

    Abstract: A method is provided for using a single-pixel imager in order to spatially reconstruct an image of a scene. The method can comprise the following: configuring a light filtering device including an array of imaging elements to a spatially varying optical filtering process of incoming light according to a series of spatial patterns corresponding to sampling functions. The light filtering device can be a transmissive filter including a first membrane, a second membrane, and a variable gap therebetween. The method further comprises tuning a controller for manipulating a variable dimension of the gap; and, measuring, using a photodetector of the single-pixel imager, a magnitude of an intensity of the filtered light across pixel locations in the series of spatial patterns. The magnitude of the intensity can be equivalent to an integral value of the scene across the pixel locations.

    Abstract: Embodiments of the present invention relate to systems and methods for spectral imaging. Electromagnetic energy emanating from an object is passed through a first dispersive element, a coded aperture, and a second dispersive element to a detector plane. A wavelength-dependent shift is created by the first dispersive element. The coded aperture modulates the image emanating from the first dispersive element. The wavelength-dependent shift is removed from the modulated image by the second dispersive element producing a wavelength-independent image measured by the detector. A spectral image of the object is calculated from the measured image, a wavelength-dependent shift of the first dispersive element, the code of the coded aperture, and a wavelength dependent shift of the second dispersive element. A spectral image can be calculated from measurements obtained in a single time step and from a number of measurements that is less than the number of elements in the spectral image.
