Light triangulation

WebDiffraction and Interference. We know that visible light is the type of electromagnetic wave to which our eyes responds. As we have seen previously, light obeys the equation. c = f λ, where c = 3.00 × 10 8 m/s is the speed of light in vacuum, f is the frequency of the electromagnetic wave in Hz (or s –1 ), and λ is its wavelength in m. WebAug 5, 2024 · Laser triangulation 3D scanning technology. Laser triangulation-based 3D scanners use either a laser line or a single laser point to scan across an object. First, the 3D scanner casts its laser onto the object. As the laser light reflects off of the 3D scanned object, its initial trajectory is modified and picked up by a sensor.
