A laser interferometer is embedded into an interference microscope to precisely determine the in-focus position of the microscope objective's reference mirror. A collimated laser beam is introduced into the microscope system and split into two beams directed toward a calibration reference surface and the interference objective. The light reflected from the calibration reference surface is returned to the camera. The light into the interference objective is focused onto the reference mirror and returned to the camera. For the purpose of calibration, the two beams are combined at the camera to produce interference fringes. When the reference mirror is in focus, the returned beam is collimated; if the mirror is on either side of focus, the beam is either converging or diverging. Accordingly, the interferogram produced at the camera reflects the in-focus or out-of-focus condition of the reference mirror. The curvature of the wavefront returned from the reference mirror is determined electronically by analyzing the interference fringes produced with the beam returned from the calibration reference surface. By minimizing the curvature of the reference-mirror wavefront as the mirror is translated along the optical path, the reference mirror can be focused with an accuracy greater than possible by visual observation. Furthermore, by automating the focusing system with a precise translation mechanism driven by closed-loop control, operator-to-operator variations are completely eliminated.

When a vehicle attempts to enter a priority road from a non-priority road, a visibility determination processing section compares moving object information on the priority road obtained from a first infrastructure facility installed near a stop position with moving object information on the priority road detected by an autonomous sensor mounted on the vehicle, and determines that the visibility is poor if the former does not match the latter or determines that the visibility is good if the former matches the latter. Then, when the former does not match the latter, the driver is informed of intersection support information. When the former matches the latter, the driver is not informed since it is determined that the driver has already recognized the information by visual observation.

A security system and method for mass transit and mass transportation whereby high capacity mobile vehicles such as ships, buses, planes, trains and subways transporting large numbers of passengers or cargo, are continuously monitored and secured. Sensors are utilized to detect and alert the presence of radioactive or explosive materials on board as well as within close proximity of the vehicle. Sensors are also used to identify and track cargo and people, such as drivers, operators, employees, crew, and passengers, and provide continuous location and tracking thereof from the point of initial entry to the final point of exit. Additionally, a global positioning system (GPS) provides location data, and wireless data and telecommunications link provides two-way data and voice communication with any designated remote location by using one of several modes of wireless telecommunication. Cameras provide visual observation within designated viewable areas, and may be activated by any detection of motion, and are infrared or night vision capable allowing viewing even in extremely poor light conditions. DVR recording allow a huge amount of video content from the cameras to be digitally recorded, then played back later for further analysis. Finally, the Security System may optionally have an Internet Protocol (IP) address thereby allowing authorized persons to access the system from secured Internet connection.

Specific embodiments of the invention are directed to improved phacoemulsification procedures involving the use of processed non-visual three-dimensional data (i.e. diagnostic scan data) to provide a surgeon with additional guidance (i.e. more than that generally obtained from visual observation of the working area) concerning the distance separating a working end of a phacoemulsification instrument and the posterior portion of the capsule of the eye during surgical procedures involving the removal of the crystalline lens of an eye (e.g. a cataract removal procedure). Such separation (i.e. distance or gap) information may be used to aid the surgeon in cutting or scoring the lens to a desired depth while minimizing the risk of penetrating the posterior portion of the capsule with the working end of the instrument. Some embodiments provide for the visual and/or auditory conveyance of distance information to the surgeon wherein visual information may be conveyed by overlaying it with real visual images of actual surface features viewed by the surgeon. Additional embodiments provide for overlaying visual representations of selected three-dimensional structure information (e.g. depths of troughs cut into the lens) with the real surface feature images viewed by the surgeon.
