3D Tracking and Position Measurement Demo
(02:01 | 34 MB)

3D Tracking - Two 4-quadrant devices track a photo-detector target in 3D space. As a result of the two separate relative position acquisitions, a real-world XYZ position measurement is possible, and the result is presented to the user in mm distance from a reference point between the devices. System performs position measurement with 16-bit precision in a 20 degree FOV cone at distances up to 10m.

Vibration Measurement with 3D Tracking Demo

3D Tracking - Two 4-quadrant devices track a photo-detector target in 3D space. This target can be attached to remote equipment to monitor the amplitude and frequency of its vibrations. In this demo we track the motion of a scroll-saw. Check the "3D Tracking and Position Measurement Demo" movie for a better description of the system.

Windshield Head-Up Display
(01:13 | 17 MB)

Our fast dual-axis devices are used to display text and various vector graphics on a windshield of an automobile. The unit is placed 20cm from the windshield surface and has a 110 degree field-of-view, allowing it to display on most of the windshield surface. This is accomplished with the combination of our MEMS device and a wide-angle lens. In production, the display unit could fit into a 2x2x2 cm cube. Power consumption is low and dominated by the laser supply.

Device Control from a Web Interface and with a Wii Remote
(01:31 | 23 MB)

Around the clock there are two live on-line demos on our website. The second one, Live Demo 2, shown in this video, provides a microscope camera view at a dual-axis 4-Quadrant device which runs continuously. A simple web interface allows users to interact with this demo. In one specific mode we allow a user (in our lab only) with a Wii Remote to control the device angle wirelessly with acceleration input, i.e. with Wii Remote motion.

Transparent Display Demo - Turning a transparent glass window into a vector graphics display. Using MirrorcleDraw software to create vector graphics patterns, text, and displaying ILDA animations, the video demonstrates displaying on a transparent glass surface which is coated with a special film.

2mm+ Biggie Mirrors and 3mm+ Jumbo Mirrors

Large Micromirrors - Latest actuators from ARIMEMS7 generation of devices provide bi-directional two-axis scanning. Largest mirrors to date in the 2mm diameter and the 3mm diameter range are mounted on the actuators and demonstrated.

To date, most generations of ARIMEMS micromirror devices provided 1-quadrant (uni-directional) scanning in two-axes, e.g. from 0° to 8° on each axis. In other words, mirror scans a laser beam only in one quadrant of the hemisphere above the chip. Most recent generation of devices includes two types of actuators shown in this video that allow 4-quadrant (bi-directional) scanning, e.g. -6° to 6° of mechanical tip/tilt on each axis.

Latest generation of ultra-lightweight micromirrors fabrication allows the use of large micromirrors in the 2mm diameter range ("Biggies,") and in the 3mm range ("Jumbos,") at relatively high scanning speeds. Above video is purposely recorded at very slow speed, with scanning driven by MirrorcleDraw software.

MTI Two-axis scanning micromirrors trajectory can be specified to fill a raster pattern of e.g. 640x480 pixels, and with fast laser modulation a grayscale bitmap image or animation can be displayed. In these videos we are demonstrating micromirror devices capable of VGA and SVGA display. A D-SUB VGA display capable plugs into our demo unit in this video so that the signal a computer's 2nd monitor is fed to our MEMS projection-based laser display unit. The micromirror device is consuming less than 6mW of power, and the overall circuit (excluding laser power,) consumes up to 250mW.

The video is distored by the camera and subsequent MPG compression, but can still give a clear view of what is possible with MirrorcleTech's devices.

Tracking and Targeting Demo
(01:21 | 7.0 MB)

TrackingDemo1 - Using video acquisition, system tracks the position of a red laser spot and directs a green laser beam to that spot with MTI's two-axis MEMS scanning micromirror.

We have also developed a PC-based MirrorcleTrack software, to control and drive MTI's gimbal-less two-axis micromirrors in connection with a video acquisition capability. The software firstly allows the user to acquire a 2-dimensional look-up table for the MEMS device, accurately mapping desired position on the display (wall) to required actuation voltages. This is done by monitoring the laser spot on the display with a video camera in a closed-loop acquisition mode. After the table of required voltages and positions is known, the device can be accurately directed to target a red laser spot that is seen inside of its display area.

Video also show the capability of the algorithm to ignore false-positive targets, whether they are spots of wrong color (another green laser,) or spots of wrong size (small red spot,) and to remain locked onto the primary target (large red spot.)
