Unformatted text preview: this object is emitted back and collected by another lens on position 3 and then collected by CCD (charge couple device) on position 4. Using CMOS technology a microprocessor on position 5 calculates the distance from the incoming light on position 4. Figure 2 is an example of laser triangulation devise to measure the distance of the material in between the two lasers. The separation between the two laser is known and the readings obtain from the two sensors are subtracted from the separation creating a thickness gaging measurement. Figure 1: Laser triangulation diagram Figure 2: Laser triangulation equipment to measure distance....
