Description
First, technical field
The present invention relates to a kind of liquid prism, more particularly, it relates to which one kind realizes light beam large deflection angle peace
The liquid prism of shifting.
2nd, technical background
With the development of science and technology optical deflection device is led in digital equipment, medical instrument, information gathering and information processing etc.
Domain has been widely used, trend that is integrated, being miniaturizated to development.The application that light beam accurately controls is increasingly
It is more, and pursue lightweight be also a kind of inevitable trend, particularly nearly ten years based on the liquid prism of electricity moisten effect into
To develop a light-weighted important directions.For traditional prism, in the case where light source is motionless, it is necessary to by means of mechanical
The mobile direction that could change light beam, its device is very heavy, but based on electricity moistening liquid prism have in these areas it is non-
Often good advantage.Liquid prism by the liquid-liquid curved surface that two kinds of immiscible liquid are formed so as to have the function of refracted light,
More importantly the liquid prism based on electricity moisten effect can change the curvature of liquid-liquid interface by varying applied voltage,
The deflection of light beam is realized, so as to realize the control to light beam.
Liquid prism has the advantages that lightweight and easy to operate, and current liquid prism is by two kinds of immiscible liquid shapes
Into one layer of liquid-liquid curved surface come realize light beam deflect, due to two kinds of liquid refractive index difference and less and electricity moisten effect
Existing saturated phenomenon, the range of deflection of light beam are limited by very large.Document " Liquid prism for beam
Tracking and steering, Optical Engineering.Vol.51, No.11, pp.114002,2012. " are open
A kind of Double-layer liquid prism, which formed by two common liq prism arrangements, but device architecture is complicated so that liquid
The application range of body prism is restricted.
3rd, the content of the invention
