摘要： OCT apparatus includes an interferometer, having an input beam splitter and a 50/50 output splitter. The splitting ratio of the input splitter may be optimized depending on the source power of light source and on the mismatch of the balanced receiver. The input splitter is a plate beam-splitter to minimize the stray reflected light in the interferometer and allow sequential operation of the apparatus in the OCT or in the confocal regime. The switching between the two regimes may be at will, or synchronous with the en-face scanning which results in quasi-simultaneous OCT/confocal imaging or in alternatives frames, confocal and OCT. By using polarization sensitive elements, two channels are provided in each regime, OCT and confocal. The two confocal polarization sensitive channels may allow adjustments of compensators prior to OCT measurements or OCT imaging.

摘要： The present invention relates to a multiple channel optical mapping apparatus which can deliver one or simultaneously at least two images of different depth resolutions or sequentially, images with different depth resolutions, or a combination of these images, or a single image with adjustable depth resolution. The multiple channels could be either multiple confocal channel and one or two optical coherence tomography channel, or two optical coherence tomography channels, or two confocal channels. The channels, either OCT or confocal can operate on the same wavelength or on different wavelengths. The apparatus can display both transversal as well as longitudinal images in an object, particularly the eye.

摘要： A wheel clamp attaches to a vehicle wheel for performing a wheel alignment on the vehicle. The wheel clamp has a body for supporting a target or measuring head, and three extendable arms slidably mounted to the body. Each arm has a gripping portion for gripping the tire's tread surface and a sidewall contact portion for contacting the tire sidewall such that the clamp body is substantially parallel to the vehicle wheel and the wheel clamp has no contact with the rim. A self-centering linkage has enmeshed gears and link arms respectively connecting the arms to the gears, such that when the gears are rotated, the arms simultaneously proportionally slide relative to the clamp body, so the gripping portions of the arms engage and grip the tire tread surface and tighten the clamp onto the tire, while the sidewall contact portions of the arms contact the tire sidewall.

摘要： A system for measuring caster trail of a wheel. The system comprises position sensing devices for sensing positional signals of the wheel and a data processing system configured to couple to the position sensing devices. The data processing system receives signals from the position sensing devices and determines spatial characteristics of a steering axis of the wheel, a reference plane and the center of a wheel. The system then determines the caster trail based on the spatial characteristics.
