a) Describe what is meant by the term Point Spread Function (PSF), explain the
relationship between the PSF and the aperture (entrance pupil) of a telescope.
You should refer to the ideas of diffraction and Fourier Optics in your answer.
b) Determine the plate scale and theoretical resolving power at a wavelength of
380 x 10-9 m of a telescope with 2 m aperture diameter and focal length of 4m.
a. What is the resolving power (in arc seconds) of a 84 cm (33 in.) telescope at a wavelength of 560 nm?
b. What do two stars 1.5 arc seconds apart look like through this telescope?
- The two points of light are well separated from each other.
-The two points of light are only just separated from each other — they are distinguishable but appear to touch.
- The two points of light are indistinguishable from each other.
4. For a space-based imaging system that uses a fixed size aperture for both visible and infrared sensors, given the characteristics listed, what would be the theoretical resolution for each of the sensors? Aperture diameter = 1.1 m. Visible wavelength = 0.5 micron. IR wavelength = 2.0 micron. Altitude = 400 km. (note: 1 micron = 1E-6 m)
