Early Color Television
Field Sequential Color Camera
This device was at the Kutztown meet. There is a hole about 1 1/2 inches in diameter in the bracket in front of the color wheel, and in the box with the chimney like thing behind the wheel. The chassis appears to be similar to the one in the Colordaptor, so this device was probably designed for NTSC.
Inside the "chimney" is a slide projector lamp. Most likely, a color slide was put in front of the wheel and a camera was focused on the slide. The wheel rotates at 180 rps so that each color filter is in front of the slide for 1/60 of a second. A sensor on the wheel generates the vertical sync for the camera. Motor speed is controlled by the chassis.
The device would create a NTSC color image of the slide.
