    • A reflective optical system is provided to control the thickness of a prism having a polarization splitter, thereby easily removing the interference effect of the light beam. A color separating member reflects and transmits the light beam within the specific range in the light beam outputted from a light source. Plural polarizing splitters transmit selectively the reflected and transmitted light beam. Plural LCoS(Liquid Crystal on Silicon) panels(54,56) receive the light beam via the polarizing splitters and also reflect the light beam together with the image information corresponding to the light beam. The difference of the light paths of the transmitted and reflected light beams through the plural polarizing splitters is above the coherence length of the light beam. The color separating member is a dichroic mirror for transmitting the blue light beam and for reflecting the green and red light beams. The polarizing splitter includes the first polarizing splitter for selectively transmitting the blue light beam. The second polarizing splitter(32) transmits one of red and green light beams and reflects the remaining one.
    • 提供反射光学系统来控制具有偏振分离器的棱镜的厚度,从而容易地消除光束的干涉效应。 颜色分离部件将从光源输出的光束的特定范围内的光束反射并透射。 多个偏振分束器选择性地透射反射和透射的光束。 多个LCoS(硅片上的液晶)面板(54,56)通过偏振分光器接收光束,并将光束与对应于光束的图像信息一起反射。 通过多个偏振光分离器的透射光和反射光的光路的差异高于光束的相干长度。 分色构件是用于透射蓝色光束并用于反射绿色和红色光束的分色镜。 偏振分离器包括用于选择性地透射蓝色光束的第一偏振分离器。 第二偏振光分离器(32)透射红色和绿色光束中的一种并反射剩余光束。

    • To provide an optical wave guide that may be produced by reproduction method in easy and simple manner, and has a structure that prevents light signal in its inside from leaking out from core, and a method for producing the same optical wave guide. A concave slot for forming a core is formed on the upper surface of a cladding substrate. And on both sides of the concave slot, cavities are formed via flat portions. An ultraviolet ray hardening type transparent resin is applied onto the surface of the cladding substrate, thereafter the transparent resin is pressed by a stamper. At this moment, a core is formed in the concave slot and excessive transparent resin is pressed between the stamper and the flat portions flows into cavities, as a result, it is possible to make the transparent resin thin in a short time. Thereby, it is possible to make the transparent resin left on the flat portions into thickness and width enough to prevent light in the core from leaking out.
    • 本发明的目的在于提供一种能够简单且容易地通过再现方法制作的光波导,并且具有防止内部的光信号从芯体漏出的结构以及该光波导的制造方法。 用于形成芯的凹槽形成在包层基板的上表面上。 并且在凹槽的两侧,空腔通过平坦部分形成。 将紫外线硬化型透明树脂涂布到包层基底的表面上,然后用压模压制透明树脂。 此时,在凹槽中形成芯,并且在压模之间挤压过量的透明树脂,并且平坦部分流入腔中,结果,可以在短时间内使透明树脂变薄。 由此,可以使留在平坦部分上的透明树脂的厚度和宽度足以防止芯中的光泄漏。
