A Method for increasing Spectacle Protective Angle Against Laser by Using Double-inclination Compound Holographic Mirrors
A method of making the double-inclination compound hologrsphic minors (DICHM) is proposed in order to increase protective angle of the spetacle against laser in this peper.The Protective angle is twice as large as that one of single holograhic minor. Experimental results show that the optical density of DICHM at the wavelength 0.53 μm is in the range 2.3 to 3.5 and the transmission of visible light is forger than 60% as the incidence angle varies from -30° to 27°.
