Abstract
A hologram fabricating apparatus includes a coherent light generator, two micro-display devices and a telecentric system. The coherent light generator provides a first coherent light and a second coherent light. Each micro-display device has a plurality of pixel elements laid thereon. The first coherent light and the second coherent light project respectively to the two micro-display devices. The telecentric system is located between the micro-display devices and a photoresist sheet to converge the projecting light on the photoresist sheet to generate interference stripes. Each pixel element may be adjusted independently to determine whether the first coherent light and the second coherent light projected to the pixel element to be projected to the telecentric system.
