The following form is to calculate the resolution of an object dependent on its size and distance.
Question: How big is an object in angular size?
Question: How big is an object in angular size?
| object: | ||
| object size: | m | |
| object distance: | m | |
| angular size: | arcsec | |
The following form is to calculate the optical resolution according to the Rayleigh criterion.
Question: What is the angular resolution of my optic?
(the angular resolution of the optic must be 3 times smaller than the angular size of the object in order to resolve it)
Question: What is the angular resolution of my optic?
(the angular resolution of the optic must be 3 times smaller than the angular size of the object in order to resolve it)
| optic diameter: | mm | |
| wave length: | mm | |
| optical resolution: | arcsec | |
The following form is to calculate the angular size of a sensor pixel according to the Nyquist-Shannon criterion.
Question: Is my sensor good enough?
Question: Is my sensor good enough?
| sensor pixel size: | µm | |
| optic focal length: | mm | |
| angular pixel size: | arcsec | |
The following result is the number of pixels in which the object is seen by the camera (optic+sensor).
