Description
Technical field
The invention belongs to optical thin film and optical precision measurement and control technology fields, are based on more particularly, to one kind
Metal receive sharp battle array electrode electricity adjust transmission optical thin film.
Background technology
Optical thin film is a kind of important optical element, has that surface is smooth, interface is clear, Refractive Index of Material connects in film
Continue in features such as interface transition.The light wave of film surface is incident on by the polarization sexual reflex of film medium and refraction, according to spy
Determining optical parameter configuration influences intensity, phase and the polarization state of traveling wave beam, obtains the reflection in specific spectral domain or transmitted light.It is typical
Function includes：The reflectivity or transmitance for enhancing wave beam carry out stationary state about to the light vector polarization behavior of reflection or refracted beam
Beam executes selective wave spectrum filtering etc. to incident light wave.The miscellaneous optical thin film developed so far is functionally

Learning reaction fluctuation influences, and optical parameter stability is insufficient, and light intensity regulating degree is unable to meet demand, it is difficult to adapt to quickly adjust and want
It asks；(2) the electric dimming film based on electrically-controlled liquid crystal, according to electricity of the intrinsic electric moment of liquid crystal material long-chain macromolecule in external electric field
Beat attribute is responded, realizes the electric modulation of its transmitance of portions incident light wave, is presented most soon in the slow of sub- Millisecond (commercialization)
Electricity adjusts response, and the controlled modulation degree of incident optical energy is low, and spectral range is limited, and liquid crystal film still shows stronger in the case where powering off state
Light transmission etc.；(3) it utilizes the hot physical property of material to realize electroluminescent light transmission rate modulation by electric heating, is constrained with thermal inertia
Time-consuming for state conversion and stabilisation, and environmental factor dependence is strong, is influenced by the photo-thermal effect of transmission light wave, and control light state will present larger
Fluctuation rises and falls, and there are the defects such as the control stability of optical parameter and control accuracy be low；(4) electric light, hot light, magneto-optic are based on
Or the dimming film of the phase transformations excitation effect such as acousto-optic, usually only there is more significant automatically controlled optical parameter in phase change zone and change,
It is commonly used for the window material of control light intensity or thang-kng spectral domain；(5) other such as based on the spectrum for example typical Fabry- of interference effect
Perot effects form the Dimming operation that specific light transports form by building Particular Intervention or diffractive light field, generally there are compared with
Strong wave spectrum and polarization selectivity and dependence, electricity adjust operation to be difficult to be unfolded in compared with wide range domain.In short, development is suitable for soon
Speed, broadband and stronger luminous power, polarization insensitive control flexible dimming film framework, are still that further development electricity is adjusted at present
The hot and difficult issue problem of optical thin film technology, receives significant attention.
