Why is the spot size of a lens diffraction limited for small aperture sizes and why is the spot size of a lens aberration limited for large aperture sizes?
Homework Answers
Part A) Diffraction is an optical phenomenon which put a limit on the total resolution of your photography . no matter how many megapixels your camera may have ? Light begins to diffract when passes through a small opening (such as your camera len's aperture). This effect is normally negligible, since smaller apertures often improve sharpness by minimizing lens aberrations. However, for sufficiently small apertures, this strategy produces reverse effect due to which your camera is said to have become diffraction limited. Knowing this limit can help maximize detail, and avoid an unnecessarily long exposure or high ISO speed. As well small aperture have size very much comperable with the wavelength.
Part B) Lens aberration is a defect of the lens due to which lens is unable to fucus all the no paraxial rays at the fucus. And this put a limit on your camera another limit known as lens aberration.

A scientist requires the construction of a diffraction-limited telescope to image small dunes on Mars. The telescope will be mounted on a spacecraft instrument platform. The spacecraft will orbit Mars at an altitude of 400 km. The dunes are 2 m in diameter (horizontal size, as seen from above). The wavelength of instrument operation is 500 nm. The large-format detector is a CCD with 4096x4096 array of pixels, where each pixel is 30x30 microns in size. The scientist requires that...

The beam emerging from a ruby laser (wavelength 694.3 nm) passes through a circular aperture 4.4 mm in diameter. (a) If the spread of the beam is limited only by diffraction, what is the angular spread of the beam?(b) If the beam is aimed at the Moon, how large a spot would be illuminated on the Moon's surface?

However, there is a basic limitation on how small a spot one can achieve with a given wavelength laser beam, ; a given diameter laser beam (D); and a lens with focal length, f. This smallest spot sizc is given by: where d is the diameter of the focused laser...

The pizza palace offers three sizes of cola. The smallest size sells for $1.99, the medium for $2.49, and the large for $2.89. Thirty percent of the drinks sold are small, 50% are medium, and 20% are large. Create a probability distribution for the random variable price and answer the following questions. a. Is this a discrete probability distribution? Indicate why or why not? b. Compute the mean amount charged for a cola. c. What is the variance in the...
