Title:
ハルトマン-シャック画像を改善するための空間フィルターとその方法
Document Type and Number:
Japanese Patent JP4017400
Kind Code:
B2
Abstract:
A system and method improve a quality of sensor image data from a wavefront emanating from an eye. The sensor image data include a pixel array of intensities. A filter array is populated with a coefficient at each position of the array and the filter array is applied to each position in the pixel array. The system includes a process and a software package adapted to perform the above method steps.
