Method of simultaneously applying multiple illumination schemes for simultaneous image acquisition in an imaging system
First Claim
1. A system for observing an object comprising:
- a first radiation projector configured to produce a first radiation signal having a first wavelength;
a second radiation projector configured to produce a second radiation signal having a second wavelength different from said first wavelength;
an image acquisition device arranged to have the object in a field of view thereof and that is configured to simultaneously capture radiation signals having said first and second wavelengths to produce an image of the object; and
a controller configured to cause said first and second radiation projectors to simultaneously illuminate the object with said first and second radiation signals and control said image acquisition device to produce the image of the object in timed relation therewith.

Abstract
A method is used for imaging applications so that one can simultaneously apply multiple illumination schemes and simultaneously acquire the images, each associated with one of the multiple illumination schemes. The illumination schemes can be, but not limited to, any combination of reflective illumination, transmitive illumination (backlighting), bright field illumination, dark field illumination, diffused illumination, cloudy-day illumination, and structured illumination. The radiation can be in any wavelengths, ranging from sonic waves, ultra sound, radio waves, microwaves, infrared, near infrared, visible light, ultra violet, X-rays, and gamma rays. The radiation of each of the illumination schemes used in an imaging application is modulated, that is, affixed with a unique signature. One or more imaging devices can be used to collect the radiating rays simultaneously after the rays interact with the object(s). The image signal(s) are then demodulated, separated into several images, each is associated with an illumination scheme, based on the signatures. A preferred embodiment is to use radiation wavelengths of 430 nm, 575 nm or 670 nm as the signatures.
