Abstract (en)

[origin: WO2009070160A1] A system includes a plurality of scanning devices and light receivers, enabling a plurality of images of a site to be displayed using output signals produced in response to light from the light receivers. To avoid crosstalk caused by light receivers receiving light emitted by a plurality of scanning devices, different wavebands of light can be applied to different scanning devices, the received light can be filtered, or the light can be supplied to one scanning device at a time to multiplex either frame-by-frame, or pixel-by-pixel, or the light supplied to each scanning device can be modulated and the received light demodulated so that an image is produced in response to light from a single scanning device. Expensive components such as laser light sources, optical detectors, a controller, and processor can be shared by multiple imaging devices to minimize the cost of the imaging system.
