    Abstract: An optical device modulates radiation such as light from an extended object and focuses it onto a single detector in such a way that the modulation gives both spatial resolution of different points on the object and spectral resolution of light coming from each point on the object. The signal received by the detector can then be demodulated to reconstruct both the spatial and spectral properties of the initial extended object. A mask pattern is used, which can be variably exposed in successive steps to produce a cyclic encoding pattern in two dimensions. For an image resolved into p X m elements, the mask need only have (2p-1) (2m-1) elements, instead of p2 X m2 modulating elements.

    Abstract: INPUT AND/OR OUTPUT GATE FOR GRID-TYPE SPECTROMETER WITH A MULTIPLICITY OF SUBSTANTIALLY IDENTICALLY SHAPED, RANDOMLY DISTRIBUTED ZONES OF A RADIATION TRANSMISSIVITY DIFFERENT FROM THAT OF THE BACKGROUND, THE TOTAL AREA OF THE ZONES BEING PREFERABLY EQUAL TO THAT OF THE BACKGROUND OUTSIDE THE ZONES. THE ZONES EXTEND ONLY OVER A SMALL FRACTION OF THE OVERALL GRID SURFACE IN ANY DIMENSION AND, WHEN THE GRID IS TO BE USED AS A COMBINED INPUT AND OUTPUT GATE IN AN AUTOCOLLIMATING SPECTROMETER, MAY BE ARRANGED IN PAIRS SYMMETRICALLY POSITIONED WITH REFERENCE TO A COMMON CNETER.

    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.
