Questions asked about optical illusions; 1: What are optical illusions? 2: What types of optical illusions are there? 3: What effects do optical illusions have on the brain 4: What causes optical illusions?
you have to process the picture in you brain to see what it is:)Its actually your brain that causes you to suffer optical illusion. Every image (color, shapes,objects) that your eyes see are processed in your brain before they are reflected back to your vision so it would be brain to eyes as opposed to eyes to brain process.
All mirages are optical illusions but all optical illusions are not mirages.
Optical art was not restricted to just one country. Optical artists were situated in America and the UK
Kerner Optical was created in 2006-08.
For the temperature you can use a thermocouple or an optical pyrometer.
PYROMETER is an instrument for measuring high temperatures esp. in furnaces and kilns
I suppose that an optical pyrometer is adequate.
Optical Pyrometer
A Pyrometer is a temperature measuring device. The word radiation in the name indicates that it does not have to be in contact with the object in order to measure the temprature. A Radiation Pyrometer has a sensor within which detects the Infra-Red radition [heat], sends that value to a mini-computer which converts that signal to a temperature reading. To use a Radiation Pyrometer, one simply points it at the object, pulls a trigger or presses a button, and reads a meter or display in order to determine the temperature of the object.

pyrometer reading is fluctuating between min to max range

No. The temperature of the sun cannot be measured by pyrometer. It is measured by a special device called Bolometer.
