### T線對和傳感器極限

(1)$$\text{傳感器解析度} \left[ \tfrac{\text{lp}}{\text{mm}} \right] = \text{像空間解析度} \left[ \tfrac{\text{lp}}{\text{mm}} \right] = \frac{1000 \tfrac{\text{μm}}{\text{mm}}}{2 \, \times \, \text{像素大小} \left[ \text{μm} \right]}$$

(2)$$\text{水平傳感器尺寸} \left[ \text{mm} \right] = \frac{\left( \text{水平像素大小} \left[ \text{μm} \right] \right) \times \left( \text{有效水平像素數量} \right) }{1000 \tfrac{\text{μm}}{\text{mm}}}$$
(3)$$\text{垂直傳感器尺寸} \left[ \text{mm} \right] = \frac{\left( \text{垂直像素大小} \left[ \text{μm} \right] \right) \times \left( \text{有效垂直像素數量} \right) }{1000 \tfrac{\text{μm}}{\text{mm}}}$$
Pixel Size (μm)Associated Nyquist Limit (lp/mm)
1.67 299.4
2.2 227.3
3.45 144.9
4.54 110.1
5.5 90.9
##### 表 1: 隨著像素大小變小，相關聯的奈奎斯特極限 (lp/mm)會呈比例升高。
