The image shows a black and white drawing of a circular object with a circle in the middle, which appears to be a radiometer. The radiometer is composed of a series of concentric circles, each with a different color, arranged in a symmetrical pattern. The circles are connected by a thin line, and the radiometer itself is surrounded by a halo of light.
