Triangulation

Triangulation

Source: Scribbr Understanding Laser Triangulation The Principle of Laser Triangulation Laser triangulation is a method used for distance measurements, commonly employing a laser beam. This technique takes advantage of the laser beam’s ability to travel in a well-collimated form over long distances. In laser triangulation, the laser beam is directed towards a point whose distance […]

Fresnel Reflections

Fresnel Reflections

Source: Kenn Hedin Kalvik Fresnel Reflections in Optics Understanding Fresnel Reflections When light, such as a laser beam, encounters a boundary between two different transparent materials, a portion of the light is transmitted through the boundary, while the rest is reflected back into the original material. This phenomenon is known as Fresnel reflections. Calculation and

Reflectivity

Source: Guardian Glass Understanding Reflectivity in Optics Reflectivity in Optics Definition Reflectivity in optics refers to the ratio of reflected optical power to the incident optical power at a surface, such as an interface between two optical media. It is commonly used for cases involving specular reflections on flat, unstructured surfaces. Reflectivity vs. Reflectance In

Reflectance

Source: Mapscaping.com Reflectance in Optics Reflectance in Optics Understanding Reflectance Reflectance is the ratio of reflected radiant flux to the incident flux at a reflecting object. It varies with the direction of incident light and the optical frequency. For polychromatic light, total reflectance is calculated as a weighted average over the optical spectrum. Types of
