摘要： The specification discloses a device and method for generating a virtual keyboard/display. By means of optical scanning, a virtual display/keyboard is generated on a physical plane through a scan laser switch. Using the code reading technology, the key position entered by the user can be read and transmitted to a computer. The disclosed device includes a first laser emitter, a second laser emitter, and a laser receiver. The disclosed method has the following steps. First, the first laser emitter performs a surface scan to generate the patterns of the keyboard/display. The second laser emitter simultaneously generates a first reflective beam and a second reflective beam when the user enters input using the virtual keyboard. Finally, the laser receiver receives the first and second reflective beams, thereby obtaining the signals entered by the user.

摘要： The optical scanning apparatus of light sources with different wavelengths relates to an optical scanning apparatus with a plurality of light sources of different wavelengths. All the light beams generated by the different light sources passing through a collimator lens, a cylindrical lens, and a beam combiner to form a single or parallel beams. The single or parallel beams pass through a reflective lens, and then pass through one or more f-&thgr; lenses installed on a rotating apparatus. Different arrangements of the reflective lens corresponding to the f-&thgr; lenses achieve three different kinds of scanning: (1) light spots corresponding to different wavelengths scanning the same positions in order (2) light spots corresponding to different wavelengths scanning different positions simultaneously (3) light spots corresponding to different wavelengths scanning the same positions simultaneously.
