论文摘要
激光导向星（LGS）在许多自适应光学系统中使用以扩展天空覆盖范围。与LGS结合使用的最常见的波前传感器是Shack-Hartmann波前传感器（SHWFS）。 Shack-Hartmann对于扩展源波前传感具有主要缺点，因为它直接采样了图像。在此程序中，我们建议使用一般的光学区分波前传感器（G-ODWFS）用于LGS的波前传感器。 G-ODWFS每个子孔只使用4个像素，几乎没有混叠噪声，因此没有虚假的低阶错误，也不需要质心校准。在此程序中，我们显示了将G-ODWF与SHWFS进行比较的模拟结果。
Laser guide stars (LGS) are used in many adaptive optics systems to extend sky coverage. The most common wavefront sensor used in combination with a LGS is a Shack-Hartmann wavefront sensor (SHWFS). The Shack-Hartmann has a major disadvantage for extended source wavefront sensing because it directly samples the image. In this proceeding we propose to use the generalized-Optical Differentation Wavefront Sensor (g-ODWFS) a wavefront sensor for wavefront sensing of LGS. The g-ODWFS uses only 4 pixels per sub-aperture, has little to no aliasing noise and therefore no spurious low-order errors and has no need for centroid gain calibrations. In this proceeding we show the results of simulations that compare the g-ODWFS with the SHWFS.
