The light optical spot area and the optical intensity distribution can be adjusted through software. The non-uniformity of response and the SNR are influenced by the noise of the detector.
光斑大小和光强分布不均的影响可以通过软件校准，象限响应率不均和信噪比受探测器噪声以及处理电路噪声的影响。
Doing so allows the optical system to reduce the error due to non-uniformity down to just 0.5 nanometers, letting researchers see at subnanometer resolutions using conventional optical microscopes.
这样做可以使光学系统减少出错，最终将这种偏差下降到仅有0.5个纳米，用传统的光学显微镜让研究人员看到亚纳米的解析度图像。
