摘要： A system including confocal and triangulation-based scanners or subsystems provides data which is both acquired and processed under the control of a control algorithm to obtain information such as dimensional information about microscopic targets which may be “noncooperative.” The “non-cooperative” targets are illuminated with a scanning beam of electromagnetic radiation such as laser light incident from a first direction. A confocal detector of the electromagnetic radiation is placed at a first location for receiving reflected radiation which is substantially optically collinear with the incident beam of electromagnetic radiation. The system includes a spatial filter for attenuating background energy. The triangulation-based subsystem also includes a detector of electromagnetic radiation which is placed at a second location which is non-collinear with respect to the incident beam. This detector has a position sensitive axis. Digital data is derived from signals produced by the detectors. In this way, data from at least one triangulation-based channel is acquired in parallel or sequentially with at least one slice of confocal image data having substantially perfect temporal and spatial registration with the triangulation-based sensor data. This allows for fusion or further processing of the data for use with a predetermined measurement algorithm to thereby obtain information about the targets.

摘要： An imaging method and system for optimum sampling, image restoration and enhancement is disclosed where imaging errors associated with scanning a fiber optic image guide are identified and filtered to restore image quality to the available resolution limit. Scanned image samples are synchronized with spot positions corresponding to the center of each fiber to avoid generating spurious data resulting from unwanted modulation of the scanning beam by the fiber optic array, manifested as large amplitude multiplicative noise. A detector, such as a position sensitive device, is utilized which allows for monitoring both spot intensity and position. Peak detection on the intensity waveform determines the instant at which the beam is to be sampled. The method applies to any imaging system where a beam of electromagnetic energy such as radiant energy is scanned through a plurality of optical fibers to irradiate the object under examination. Various embodiments are disclosed which, depending upon application requirements, affect the level and sophistication of the signal processing hardware. The imaging system may utilize grey scale, color, motion (as in a Doppler vibrometry system) or 3D information.
