“…In order to improve the energetic efficiency and the display performance of the proposed device, the emitted Gaussian beams were reshaped by only passing DOE that performed what is called Gaussian to Top Hat conversion in the distribution profile of the beam, through special phase. Such DOE is called Top Hat DOE [16,17]. The Top Hat distribution has rectangular cross section that is similar to the area of the surface of the DMD.…”

One of the major power consuming components in a computer is its display unit. On average the screen consumes ten times more power than the DSP processor itself. Thus, reducing the power consumption should be one of the most important tasks in the development of low power consumption computing systems. In this paper we present one possible solution involving micro projection device based upon lasers and a digital light processing (DLP) matrix which is a matrix of electrically controllable mirrors capable of translating electrical signal to a time varying projected image. It can serve to substitute a screen and consume ten times less power than a conventional screen. The described device is a multifunctional highly efficient customized DLP light engine being capable of serving as an image projector and simultaneously to support range and topography estimation measurements
