Hi, Mohan

The sensor’s Nyquist rate (the sampling frequency, or maximum resolution you could hypothetically get) for the your camera depend from pixel size of sensor. You should know the type of sensor and the exact size of pixels. Nyquist rate (lpp) = 1/2*pixel pitch, lines per millimeter, although aliasing, colour interpolation and the multiplication of contrast functions reduce the real detail it can actually resolve.

Distance = 0.5 m -> 500 mm

From the geometry of Fig. 2.3,(see reference)

7mm/35mm=z/500mm, -> z = 100 mm.

So the target size is 100 mm on the side.

Now, we have a total of 1024 elements per line,

So the resolution of 1 line is 1024/100 = 10 elements/mm.

For line pairs we divide by 2, giving an answer of 5 line pairs/mm.

Therefore, number of line pairs per mm = 5 line pairs/mm.
