Background technique
Telescope is a kind of optical instrument that remote object is observed using lens or reflecting mirror and other optical devices.Benefit
It is reflected by the concave mirror with the light refraction or light by lens and feeds them into aperture and assemble imaging, using a magnification eyepiece
And it is seen.Also known as " a thousand li mirror ".Prism, a kind of transparent substance by intersecting two-by-two but plane not parallel each other surrounds,
To be divided or make light beam that dispersion occurs.Prism is the polyhedron that transparent material (such as glass, crystal) is made into.In optical instrument
Middle application is very wide.Prism can be divided into purposes several by its nature.For example, complex light is decomposed into spectrum in spectral instrument
" dispersing prism ", more common is equilateral prism；Change the carry out side of light in the instruments such as periscope, binocular
To being generally used right-angle prism so as to adjust the title " total reflection prism " of its imaging position.The effect of reflecting prism: in benefit
When reflecting prism (or reflector plate) being used to carry out ranging as reverberation, reflecting prism receives the optical signal that total station issues, and
It is reflected back towards.Total station issues optical signal, and receives from the reflected optical signal of reflecting prism, calculates the phase of optical signal
Displacement etc., to acquire the time that light passes through indirectly, finally measure total station to reflecting prism distance.Light is in reflecting prism
Propagating the excess time used can make institute's ranging from a certain numerical value of increase, that is to say, that the spread speed of light in glass is than sky
Slow in gas, usually our this numerical value increased is referred to as prism constant.
