quality optical prism on sales introduces the basics of prism

Do you know the basics about prisms? Today, the editor of quality optical prism on sales will take you to a simple understanding.
The function of the reflecting prism: When using the reflecting prism (or the reflecting sheet) as the reflector for distance measurement, the reflecting prism receives the light signal from the total station and reflects it back. The total station sends out an optical signal, receives the optical signal reflected from the reflecting prism, calculates the phase shift of the optical signal, etc., so as to indirectly obtain the light passing time, and then measures the distance from the total station to the reflecting prism.

Principle of reflective prism: The working principle of reflective prism is actually the law of reflection and refraction of light. When light is reflected in the same medium, its reflection angle and incidence angle are equal; when light is incident from one medium perpendicular to the two medium planes to another medium, it will not be refracted.
The above is the small series of quality optical prism on sales: a brief introduction to the basic knowledge of prisms.
