Frequently Asked Questions (FAQ)
How do you calculate angular resolution?
- To calculate angular resolution, use the formula: θ = 1.22 * λ / d. where λ is the wavelength of light and d is the diameter of the lens aperture.
What does angular resolution measure?
- Angular resolution is a major determinant of image resolution. It is the capacity of an image-forming device such as an optical or radio telescope, a microscope, a camera, or an eye, to separate two objects located at a small angular distance.
Where does the 1.22 come from in the formula for angular resolution?
- The factor 1.22 in the angular resolution formula is derived from a calculation of the position of the first dark ring surrounding the central Airy disc of the diffraction pattern.
What is the resolution formula?
- To calculate angular resolution, use the formula: θ = 1.22 * λ / d. where λ is the wavelength of light and d is the diameter of the lens aperture.
