What is the role of the laser in an AFM experiment?
The most common use of a laser in an Atomic Force Microscope (AFM) is to generate a coherent beam of light that is reflected from the back of the AFM probe and onto a photodetector. As the AFM cantilever moves up and down, or twists left and right, the reflected beam traverses the photodetector creating a change in the voltage output from the segments (quadrants) of the photodetector. This difference signal is normalized to the total voltage output (the “sum”) and that normalized difference value is used as a measure of the degree of vertical deflection of the AFM probe. The coolest part of this system is the incredible sensitivity achieved by the laser behaving like a mechanical lever. Tiny motions of the AFM probe result in much larger motions of the laser traversing the photodetector. In this way one can measure nanoscale topographical changes or picoNewton forces on a surface. Lasers can also be used in the AFM to: cause thermal bending of AFM cantilever for remote mechanical control. heat the cantilever for thermal effects.

Where is the air intake temperature sensor on a pug 205 gti 1.9 H reg?
Hi, it's located in the AFM. Generally not replaceable though as it's under the laser cut resistor plate and hard to get at. Best to try and and get a second hand good one (AFM) Dave

Location of air intake temperature sensor 22re?
Its built into the AFM
Is it which one it would be or which one would it be?
Answer: Which one would it be. It can be both actually. You can use 'which one it would be' as a statement such as - Between these two colors I wonder which one it would be - and use 'which one would it be' as a question such as - Between these two colors, which one would it be?
How would one use an Actiontec GT701 WG modem?
One would use the modem for many things. They would use it for setting up a firewall for internet security and they would use it for connecting with the network.
