Concept explainers
(a)
To Calculate: The resolution of the lens.
(a)
Answer to Problem 62A
Explanation of Solution
Given:
Aperture of the camera,
F-ratio of the lens,
Diameter of the lens,
Distance of the CCD detector,
Formula Used:
Resolution of lens can be obtained by:
Here, d is the diameter of the lens,
Calculations:
Substitute the values and solve:
Conclusion:
Thus, the resolution of the lens is
(b)
To Compare: The size of the pixel with width of the central spot.
(b)
Explanation of Solution
Given:
Side of a pixel,
Resolution of the lens,
Formula Used:
Width of the central spot can be obtained by:
Here, R is the resolution.
Calculations:
Substitute the values and solve:
Now, take the ratio of the width of central spot and size of the pixel:
Conclusion:
Thus, in ratio of width of the central spot and size of the pixel is 1.42.
