真三维显示器中的同步照明光学系统

在基于多投影机旋转屏的真三维显示器中需要有一种高亮度、窄脉冲工作的白光光源。提出了一种同步照明光学系统,它采用高亮度、连续白光UHP灯作为投影光源,场镜与球面反射镜绕屏幕转轴交替排列,两个透镜组与屏幕同步转动,只有在屏幕正对着投影机时,光束才能从对应的场镜出射照明相应的投影机。该照明光学系统仅用一个光源就能满足真三维显示器中所有投影机照明的需要,并从结构上保证了屏幕转动与投影机投影之间严格同步。该系统成功地应用到了基于多投影机旋转屏的真三维显示器中,三维图像清晰明亮,色彩丰富。论述了系统的工作原理和系统结构,并对投影结果进行了分析。

Synchronous illumination optical system of three-dimensional volumetric display

An ultrahigh-bright white light source with narrow pulsed illuminating function is needed in the three-dimensional volumetric display utilizing multiple projectors and rotating screen.A new synchronous illumination optical system is presented.In this system,an ultrahigh-bright continuous white UHP lamp is used as light source,and multiple groups field lens and spherical reflectors are arranged around the axis of rotating screen alternatively.Two lens groups rotate with screen synchronously,and the beam of l...
