The maximum input gray level (MIGL) in the projected patterns can be reduced to an optimal trade-off point, below which the image intensity signal-to-noise ratio would diminish the advantage of further MIGL reduction. Measurement simulations using ten MIGLs (75 to 255) demonstrated reduction in RMS errors for ambient illuminance of 600, 700, 800 and 900 lx, from 0.31, 0.45, 0.75 and 1.21 mm, respectively, to 0.2 mm. The advantage of the approach was confirmed in real measurements of a flat plate and human mask.","PeriodicalId":91154,"journal":{"name":"Optomechatronic Technologies (ISOT), 2010 International Symposium on : 25-27 Oct. 2010 : [Toronto, ON].

The planar rotor described in this paper rotates due to nine electromagnets evenly spaced around the rotor. An optical encoder feedback system is designed and fabricated that controls the frequency of the levitating rotor. An improved driving circuit allows current to flow through one phase at a time, which produces a magnetic field strong enough to spin the rotor. Experiments suggest that the optical encoder feedback control system can do reference tracking on the levitating rotor system. The designed control algorithm can drive the rotor to specified reference frequencies up to 1.3 Hz using the optical encoder measurements. An improved control algorithm and an actuator system with higher switching speed are implemented to observe faster system response.","PeriodicalId":91154,"journal":{"name":"Optomechatronic Technologies (ISOT), 2010 International Symposium on : 25-27 Oct. 2010 : [Toronto, ON].

The most important element to achieve the Nano-CMM is the probe for sensing surfaces of 3D components. In this study, laser trapping probe, which is the micro-sphere trapped in air by optical radiation pressures, is proposed as a novel probe. In this paper, micro-groove structure on micro electromechanical system (MEMS) device is measured by using laser trapping probe with circular motion, which is improved to have same sensing property by use of the element of radial polarization. The probe has a diameter of 8 μm while conventional micro probes have a diameter of several tens of μm. The small probe makes it possible to measure narrow space of 50 μm. Moreover, the probe enables to measure specimen regardless of the approaching direction. This shows the potential that laser trapping probe enables to measure any micro structure with same manner. Although there are some conjectures to resolve, it seems that the laser trapping probe is validity as a probe for Nano-CMM.","PeriodicalId":91154,"journal":{"name":"Optomechatronic Technologies (ISOT), 2010 International Symposium on : 25-27 Oct. 2010 : [Toronto, ON].

Our implementation, using OCM, provides not only high performance, but also flexibility and a greater robustness, all of which are necessary to embed vision sensors in mobile robots and vehicles. The prototype sensor we implemented runs stereo matching with images of 752 by 480 pixels via image sensing chips, at a frame rate of 60 fps. The maximum disparity, using the current design, is 127 pixels at an operating frequency of 53MHz on the FPGA.

The wire undergoes change in the radius of curvature as it rotates, and when light is irradiated at the point where the wire is leaving the wheel, it undergoes phase transition and straighten: causing a rotating force to the wheel. In the experiment a rotational speed of 135 to 140 rpm was observed at the smaller wheel for a single loop of 0.3 mm-diameter SMA wire.","PeriodicalId":91154,"journal":{"name":"Optomechatronic Technologies (ISOT), 2010 International Symposium on : 25-27 Oct. 2010 : [Toronto, ON].

To image the surface roughness, by which the object looks like orange peel, we employ a patterned illumination with phase shifting. The object can be exposed to various illumination conditions according to the phase of pattern lighting. By ac hieving a series of images and analyzing the phase, an image can be synthesized as specific phase selectively. The grade of su rface quality in terms of orange peel is then evaluated based on a specific phase.

Refractive index changes in the microring due to free carriers generated by two photon absorption are used to switch the probe beam in and out of resonance.
