Early Color Television Field Sequential Color CameraThis 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. 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 144 rps so that each color filter is in front of the slide for 1/48 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 color image of the slide. On loan to the museum by Mike Molnar |
