Embodiment Construction
[0024] figure 1 The reference number 10 in generally identifies a hand-held device such as a personal digital assistant, wherein a device such as figure 2 Shown is a lightweight, compact image projection arrangement 20, the handheld device for projecting two-dimensional color distortion-free images at variable distances from the device. As an example, image 18 is located within a working range of distance relative to device 10 .
[0025] Such as figure 1 As shown, the undistorted image 18 extends within an optical horizontal scan angle A of the image extending in the horizontal direction and within an optical vertical scan angle B extending in the vertical direction. As described below, the image consists of illuminated and unilluminated pixels on a raster pattern of scan lines swept out by the scanner in arrangement 20 .
[0026] The parallelepiped shape of the device 10 represents only one form factor of the housing in which the arrangement 20 can be realized. The devic...
