What can cause distortion or magnification in an x-Ray?
Size distortion has to do with magnification. Increased SID decreases distortion especially is it's within the appropriate range for the part. (ie 40/72). Increasing OID is most detrimental and increases distortion. Angling the tube increases SID HOWEVER, it increases distortion. Angling the tube also increases distortion for shape. If the part and IR are not properly *aligned or *centered, this also increases distortion. Shape distortion has to do with elongating or foreshortening a part on the image.
What is the difference between distortion and dispersion?
shape will be changed
Difference between spectrum analyzer and distortion analyzer?
The spectrum analyzer is used to do distortion analysis to the signal. Due to the fact that we don't have a pure generated signal. In reality, there must be some distortion. The distortion analysis is important in the communication field as well as in electronics.
What is the difference between the modulating signal and the demodulating signal in output of the detector?
Distortion.
What is the clear definition of projective distortion?
Due to perspective projection, an object is projected in a different way in the two images using two cameras.
What is coarse frequency offset?
the frequency difference between the transmitter and the receiver without any noise or distortion
What is the difference between frequency distortion and phase distortion?
A signal that suffers frequency distortion has one of its frequencies shifted higher or lower. A signal that suffers phase distortion has one of its frequencies shifted in time compared to others. Take, for example, a square wave. Shift the phase of the primary harmonic and you have a mess that sounds the same pitch but different. If you shifted the frequency, it would sound higher or lower.
What is the difference between subjective and objective mineral properties?
subjective is exactly how it is without any distortion and objective is with the mind and opinion.
Why are photographers concerned about the Camera angle?
Changing the angle of a camera can introduce distortion in the image. When you take a picture of a tall building, and you are close to the base of that building, the image will appear to be wider at the base than at the top. Most good image software can help to reduce this distortion and is usually called perspective correction, or something similar.
What are the 4 types of distortion of a map?
The four types of distortion in maps are shape distortion, area distortion, distance distortion, and direction distortion. These distortions occur due to the challenge of transferring a three-dimensional surface onto a two-dimensional map.
Do stars look different from space?
The only difference of the twinkling caused by the distortion of light due to the earths atmosphere which is not present in a vacuum.
What is an excuse?
Basic definition: Something people use to remove the blame from them to make themselves look good. Complex definition: The reduction, expansion or distortion of 3 dynamic factors: perception, perspective and instance /distance (space-time continuum). Example: The concept (perception: constructed idea, not proven logic) of politics from an objective view (perspective: majority, not minority) highlights importance/negligence/relevance/ordinance (distortion of space-time: instance, distance, importance) of participation from citizens.
