Compressive sensing optical design and simulation tool
| DWPI Title: Method for designing computational/compressive imaging optical systems e.g. spherical/parabolic lenses, involves determining system transfer function for designing computational imaging or compressive imaging optical system |
| Abstract: A system or method for designing optical systems includes generating a mathematical model of an imaging system; tracing a plurality of light rays from a source through the model of the imaging system in a forward direction and a backward direction incident upon an arbitrarily defined detector location; calculating the total light rays incident upon the arbitrarily defined detector location in response to the plurality of light rays; tracing a series of calibration images first through the computational or compressive imager mathematical model; measuring an output set of parameters based on a plurality of detected rays calibration images at the defined detector location; storing the output set of parameters in software, and determining an estimated system transfer function. |
| Use: Method for designing computational/compressive imaging optical systems e.g. spherical/parabolic lenses and mirror. |
| Advantage: The method enables using parallel calculating capabilities to reduce time required to simulate calibration and test images needed to evaluate performance of a computational or compressive imaging system, and using performance metrics to provide quantitative evaluation of the performance of the computational or compressive imaging system. |
| Novelty: The method involves tracing a series of calibration images through a computational imaging system mathematical model or compressive imaging system mathematical model using total light rays incident upon an arbitrarily defined detector location. An output set of parameters is calculated using a computer based on a set of detected rays or calibration images at the arbitrarily defined detector location. The output set of parameters is stored in memory. System transfer function used to design an optical system using the output set of parameters is determined. A computational imaging or compressive imaging optical system is designed using the determined system transfer function. |
