Products/Services for Psd Distance Measurement

  • Interferometers-Image
    Interferometers - (109 companies)
    Interferometers measure distance in terms of wavelength and determine the wavelengths of light sources. They use two or more flat mirrors to split off or pick off beams from a light source such as a laser, lamp, or star. The beams are then combined...

...of triangulation. Light emitted from the sender hits the object and bounces back at an angle to the position-sensitive device (PSD). The PSD uses the angle of reflection and the position of the light spot to calculate the distance to the object. The OD can calculate down to 3 um. A version with a plastic...
