A three-dimensional optical mouse device with a Micromirror Array Lens(MMAL) is provided. To have the three-dimensional optical mouse system, a three-dimensional imaging device is used for detecting the motion of optical pointer or fingers of the user and gives a location of the pointer to computer working as a pointing device in three-dimension. This three-dimensional pointing system uses three-dimensional imaging device using MMAL with variable focal length.

A beam focusing and scanning system using a micromirror array lens (optical system) includes a light source configured to emit light and a micromirror array lens, including at least one micromirror, optically coupled to the light source, configured to reflect the light onto a projection medium (projection plane). The optical system also includes at least one actuating component coupled to the at least one micromirror, configured to move the at least one micromirror to enable the at least one micromirror to focus the light on the projection medium. The advantages of the present invention include high speed variable focusing and scanning, large focal length variation, phase compensation, high reliability and optical efficiency, low power consumption and low cost.

A virtual keyboard input system using three-dimensional motion detecting by variable focal length MMAL is provided. The compactness of the virtual keyboard input system is accomplished by the variable focal length MMAL performing three-dimensional imaging function. Since the three-dimensional imaging process occurs in a very short time scale, the system can determine the motion of the input by the user and track the motion of the user in real-time based response. Image processor can determine which input is occurred at the moment and the time-dependent profile of the motion itself. The input system gives an output just like a conventional keyboard and a mouse system.

A pocket-sized two-dimensional image projection device adapted to a portable device is invented. The pocket-sized two-dimensional image projection device projects two-dimensional image on a projection surface with arbitrary profile and arbitrary distance from the projection device, and arbitrary attitude about the projection device. The position, profile, and attitude of the projection surface about the projection device can be arbitrary because the projection surface is not embodied in the projection device to reduce size of the device. Each micromirror array lens has the ability of scanning and focusing on the projection surface. The focusing on the projection surface can be achieved by automatic focusing function of micromirror array lens. Therefore, an in-focused two-dimensional image can be displayed on arbitrary projection surface. Also, this invention makes a brighter and less power consuming display device, which give an advantage for the portable device application.
摘要:
A two-dimensional image projection device using array of micromirror array lenses and a random scanning technique is invented. Using the random scanning technique, the light efficiency is nearly doubled than that of the prior art. The invention makes a brighter and less power consuming display device possible. Because each micromirror array lens of array of micromirror array lenses can scan whole image plane, a fast self diagnosis and correction technique can be introduced in displaying device. The Self diagnosis and correction technique makes display device to maintain image quality even a few tens percent of micromirrors do not work properly. Owing to the scanning characteristics of micromirror array lens, the image projection device can express the same number of pixels image with less number of micromirrors than the prior art. This also enables small sized two-dimensional image projector, which can be incorporated in portable electronic equipments.

The display system also includes an array of micromirror array lenses optically coupled to the display device, each micromirror array lens of the array of micromirror array lenses placed at a different location with respect to the display device, configured to focus the at least one two-dimensional image from each different location to provide a three-dimensional (3-D) image. The advantages of the present invention include increased viewing angles and wide depth range of three-dimensional images.

A micromirror control system includes a bottom layer configured to support the micromirror control system including a stopper plate coupled to the bottom layer at a first end, configured to rotate about an axis. The micromirror control system also includes a micromirror, communicatively coupled to the stopper plate on a bottom side, and including a reflective top side configured to reflect light. Rotation of the stopper plate about the axis into contact with the micromirror is configured to adjust an orientation of the micromirror. In one aspect, the micromirror control system also includes an actuating device, communicatively coupled to the stopper plate, configured to control the rotation of the stopper plate about the axis. The advantages of the present invention include the ability to finely control translation and rotation of a discretely controlled micromirror.
摘要:
An optical pick-up device comprising at least one micromirror array lens. The micromirror array lens enables focusing, tracking, and/or tilt compensation in the optical pick-up device without macroscopic motions. The micromirror array lens provides the device with a simple structure, which can reduce the size, weight, and cost of the recording/reproducing system. The device is also durable for vibration. Optical pick-up devices using an array of micromirror array lenses can increase the recording/reading speed without macroscopic motions. The recording/reading speed can be increased by adding more micromirror array lenses to the lens array. The present invention can also be used to record/read information on/from a multi-layered optical disc.
摘要:
Automatic focusing system is provided which comprises a mirror or a plurality of mirrors with a translation device. Automatic focusing can be made by the translation of mirror because focal plane can be changed by the translation of mirror. The translation device makes its motion by the electrostatic, electromagnetic and/or electrothermal forces. The mirror is controlled by the electrical signal from the image processor to get an in-focus image. Also the mirror can be controlled discretely. The image shift by translation is compensated by tilt of mirror and/or image processing.
