Optical design techniques for providing favorable fabrication characteristics

摘要

Disclosed are methods and techniques for providing favorable fabrication characteristics for optical elements. One method includes providing a desired integrated computational element (ICE) design comprising a plurality of layers, each layer having a design thickness, randomizing the design thickness of each layer of the desired ICE design to simulate a fabrication error in each layer, thereby generating a plurality of randomized ICE designs, calculating a standard error of calibration between each randomized ICE design and the desired ICE design, correlating the standard error of calibration between a given layer of the desired ICE design and the fabrication error of each corresponding layer of each randomized ICE design, and ranking the plurality of layers of the desired ICE design based on the sensitivity to changes in the standard error of calibration.

1. A method of fabricating an optical element, comprising:
randomizing a design thickness of each layer of a desired integrated computational element (ICE) design to simulate a fabrication error in each layer, thereby generating a plurality of randomized ICE designs; calculating a standard error of calibration for each randomized ICE design; correlating the standard error of calibration for each randomized ICE design with the fabrication error of each corresponding layer of each randomized ICE design; ranking the plurality of layers of the desired ICE design based on a sensitivity of the standard error of calibration to the fabrication error of each corresponding layer; and depositing at least one of higher ranking layer in the plurality of layers of the desired ICE design on an optical substrate at a slower deposition rate compared to at least one lower ranking layer.
