WebProfile projectors (optical comparators) are a type of optical measuring instrument. The measurement principle is similar to that of optical microscopes. The target is placed on the stage, and a light is shined on the target from underneath. This causes the target's profile, or shadow, to be projected on the screen. A telecentric optical system ... WebOptical fiber -based optical profilometers scan surfaces with optical probes which send light interference signals back to the profilometer detector via an optical fiber. Fiber-based probes can be physically located hundreds of meters away from the detector enclosure, without signal degradation.

WebOp Amp as Comparator Circuit Working Operation In general, the output of an Op-amp fluctuates positive and negative to an extreme voltage that is approximately equal to the supply potentials. If a 741 op-amp is connected to a +/-18V, then the maximum output voltage is given as +/-15V. WebThe comparator circuit work by simply taking two analog input signals, comparing them and then produce the logical output high “1” or low “0“. … When the analog input on non-inverting is less than the analog input on inverting input, then the comparator output will swing to the logical low.
