Spread Out Resolution For Free

What does better angular resolution mean? you can see smaller details. True or false: X rays from astronomical objects can only be detected from telescopes in space.

Resolving power is another important feature of a telescope. This is the ability of the instrument to distinguish clearly between two points whose angular separation is less than the smallest angle that the observer's eye can resolve.

The Hubble Space Telescope (HST) has a highest resolution of about 0.03 arcseconds, while the Very Long Baseline Array (VLBA) makes images with a resolution smaller than 0.001 arcsec. So, the VLBA has the HST beat when it comes to picture resolution.

Resolution, limit ofThe least separation of two images so that they are seen as separate when viewed through an optical instrument.The limit of resolution is greater the larger the aperture of the system. Syn. resolving power; resolution threshold.

Dmin= (1.22 03bb)/(2 sin 03b2) Therefore dmin= (1.2203bb)/ (2n sin03b2) is known as numerical aperture of the objective lens. Resolving Power(R.P) of a microscope 221d (1/dmin). This implies resolving power decreases as the distance increases.

In order to increase the resolution (d=03bb/2 NA), the specimen must be viewed using either shorter wavelength (03bb) light or through an imaging medium with a relatively high refractive index or with optical components which have a high NA (or, indeed, a combination of all of these factors).

The resolving power of an objective lens is measured by its ability to differentiate two lines or points in an object. The greater the resolving power, the smaller the minimum distance between two lines or points that can still be distinguished. The larger the N.A., the higher the resolving power.
