    摘要: A laser scanning optical microscope comprises a first optical scanning device for generating a laser beam and scanning a specimen with the laser beam in a direction at a preselected frequency. A drive circuit controls the first optical scanning device to scan the specimen with the laser beam. A pair of second optical scanning devices scan the laser beam in directions perpendicular and parallel to the scanning direction of the first optical scanning device at two frequencies lower than the preselected frequency. A light receiving device receives light reflected or transmitted by the scanned specimen and produces a photoelectric signal. A signal processing device converts the photoelectric signal obtained from the light receiving device to a standard television scanning signal corresponding to a laser beam scanning pattern obtained with the first optical scanning device and the pair of second optical scanning devices.

    摘要: A laser beam emitted by a laser light source is scanned in a series of small, high-speed oscillations in a first scanning direction by an acousto-optical deflector, and scanned at a lower frequency in a second direction perpendicular to the first scanning direction by a vibration mirror galvanometer, and scanned at yet a lower frequency in a third direction, parallel to the first direction, by a mirror galvanometer in order to enable high-precision scanning, and is projected onto a prescribed region of an eye. Light reflected by the eye passes, via the mirror galvanometers and, through a confocal optical aperture and is converted to an electrical signal by a photosensor. The signal is then converted by a signal processor to a standard television line format.

    摘要: A first external storage device which may be a CD stores data representing standard map of a particular area and that required for guidance, and a second external storage device which may be an IC card stores individual data which cannot be complemented by said data representing the standard map and said guidance data. Since the data is stored in both CD and IC card, the number of data can be reduced. This makes the operation simpler and enables a data that meets the demand of a user to be selectively supplied to the user. In consequence, guided navigation is made possible from any starting point to a destination, and data updating can be made relatively easy.
