This paper presents an electronically tuneable light filter. The filter can separate a very narrow band of light in an electronically controlled manner. The separated band of light is focused as an image. The filter can work as a very fast shutter too. A speed of that shutter can reach 1 microsecond or better. The term 'light' is understood herein as the visible and infrared regions of electromagnetic radiation. The paper also explains the physics of the filter and shows mathematical analysis of image generation.
