巴可DLP色轮 研究颜色相加混合的一种实验仪器。色轮包括一个变速马达，转速约每分钟300～5000转。马达的中心轴装着一个画有360°刻度的圆盘。不同颜色的纸盘互相交叉固定在圆盘上。当马达旋转时，不同的颜色连续刺激视觉器官，即产生相加混合的效果。色轮除作颜色混合的实验外，还可作闪光融合等的实验用。 一般来说，色轮（COLOR WHEEL）是由红、绿、蓝、白等分色滤光片的组合，可将透过的白光进行分色，并通过高速马达使其转动，然后顺序分出不同单色光于指定的光路上，最后经由其它光机元件合成并投射出全彩影像。

     Barco DLP color wheel An experimental instrument for studying color blending. The color wheel consists of a variable speed motor that rotates about 300 to 5000 revolutions per minute. The central axis of the motor holds a disk with a 360 degree scale. Paper plates of different colors are intercrossed and fixed to the disc. When the motor rotates, different colors continuously stimulate the visual organs, that is, the effect of adding and mixing. The color wheel can be used in experiments such as flash fusion in addition to the experiments of color mixing. In general, COLOR WHEEL is a combination of red, green, blue and white color separation filters. It can separate the white light through it, rotate it through a high speed motor, and then sequence the different single colors on the specified light path.
