It relates to being clear and understandable. For example you would need coherence between two people working on a detailed or complex project, so they both know what they are doing and what the other is doing and the overall objective.

What do lasers convert electrical signals into pulses of?
coherent light
What is coherent and non coherent detection reception?
1AnswerA coherent detector uses the knowledge of the phase of the carrier wave to demoduleate the signal.it's simply a product device , which multiply the AM signal by a sinusoidal signal having the same carrier frequency , followed by a low pass filter ( LPF). The product will shift the AM signal to 0 Hz and double carrier frequency , and the LPF will eliminate the later component.2ANSWER:Coherent detectioninCoherent detectionrequires carrier phase recovery at the receiver and hence, circuits to perform phase estimation.Sources of carrier-phase mismatch at the receiver:inPropagationtalking causes carrier-phase offset in the received signal.inThe oscillators at the receiver which generate the carrier signal, are not usually phased locked to the transmitted carrier.coherent detection: Huge need for a reference in phase with the received carrierinLess complexity compared to incoherent detection at the price of higher error rate.Coherent ( synchronous ) detection: in coherent detection , the local carrier generated at the receiver in phase locked with the carrier at transmitter .Non coherent ( envelope ) detection : this type of detection does not need receiver carrier to be phase locked with transmitter carrier
Why two independent sources cannot behave as a coherent sources?
Light is emitted due to the de-excitaton of electrons from higher orbits of the various atoms of the light source.The de-excitation can also be to different levels in different atoms resulting in emission of different wavelengths.A light source will have numerous atoms in it.When you take two light sources it is not possible for all the atoms to get de-excited to the same shell at the same time(causing phase difference) that is why two independent sources cannot be coherent.
Can you put a LED inside a laser housing to focus it into a beam just like a laser diode would?
No. Unless the LED is specifically a laser, you can not make it focus like a laser by putting it in a housing. A laser produces coherent light, which is why it acts like a beam. A normal LED is not coherent, and you can not make it so. Although you can not make a collimated incoherent light beam able to travel similar distances as a collimated laser beam, you can collimate incoherent light into a beam which would travel some distance with a small amount of divergence.
What is a super luminescent diode?
With their emission properties Superluminescent Light-Emitting Diodes (SLEDs) are closing the gap between Laser Diodes (LDs) and Light Emitting Diodes (LEDs).They offer the broadband optical spectra of LEDs and the spatial coherence of LDs. Compared to Laser Diodes and LEDs, SLEDs can be understood as • Spatial coherent broadband laser diodes with a beam-like output • Temporal incoherent laser diodes with a broadband spectrum • Speckle-free laser diodes with a short coherence length • Spatial coherent LEDs with a beam-like output
What is the root word for coherent?
The root word for coherent is "cohere," which comes from the Latin word "cohaerere," meaning "to stick together" or "to be connected."
Why were the cultures of the Phoenicians and polynesiansn?
Why indeed! If you have a real question in mind, try expressing it so that it has meaning, and we may be able to help - a coherent question invites a coherent answer.
What is the meaning of two coherent source?
The meaning it carries by saying that a source A and Source B are coherent source means that for a certain place of consideration the light from these sources arrive at the same phase or at such phases whose difference doesn't change over time.
What does bo is twi mean?
"Bo is twi" doesn't have a known meaning. It might not be a coherent phrase in any language.
What is the suffix of coherent?
The suffix of "coherent" is "-ent."
Is coherent a verb?
No, "coherent" is not a verb. It is an adjective used to describe something logical or consistent.
What is the definition of a Coherent Laser?

What is d meaning of ugarsay anecay agassebay?
The sentence "ugarsay anecay agassebay" does not have a specific meaning in English. It appears to be a jumble of random letters that does not form a coherent phrase or word.
What is a statement that lacks any meaning called?
A statement that lacks any meaning is called a "meaningless statement" or "nonsense." It does not convey any coherent message or make logical sense.
How would you use the word coherent in a sentence define coherent?
"Please give a coherent definition of the tiny ear bones." Coherent means to make it easy to understand or to see.
What does coherent means in the law?
Coherent means 'adapted to the understanding'.
