MULTISPECTRAL IMAGING APPARATUS
First Claim
1. A lens compound for connecting to an interchangeable lens mount of a digital camera having a single image sensor, the lens compound comprising:
- a body;
a single mount connecting ring mounted on said body for connecting to the lens mount of the digital camera;
at least two lenses of substantially identical focal length mounted in said body; and
a different single or multi bandpass filter associated with each of said lenses, allowing the passage of at least one visible band and one non-visible band, selected from the group consisting of near infra-red bands and ultra violet bands of light, through the filters to the sensor;
wherein the lenses are of substantially identical field of view and substantially identical image circle at a sensor plane of the camera.

11. A method for capturing multi spectral images, the method comprising:
-
capturing images on a single image sensor through at least two lenses of substantially identical focal length, wherein the lenses are of substantially identical field of view and substantially identical image circle at a sensor plane; each said lens being associated with a different single or multi bandpass filter; passing at least one visible band and at least one non-visible band, through said filters to the sensor; and saving said captured images from the multiple lenses in a single image file. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A multi spectral camera comprising
a digital camera having an interchangeable lens mount, a shutter and a single sensor; - and
a replaceable lens compound including; a body; a single mount connecting ring mounted on said body for connecting to the lens mount of the digital camera; at least two lenses of substantially identical focal length mounted in said body, each said lens mounted with its focal center disposed in front of the center of its respective portion of the sensor; a different single or multi bandpass filter associated with each of said lenses, allowing passage of at least one visible band and at least one non-visible band, selected from the group consisting of near infra-red bands and ultra violet bands of light, through said filters to the sensor; wherein the lenses are of identical field of view and substantially identical image circle at a sensor plane of the camera. - View Dependent Claims (20, 21, 22)

23. A method for providing post-acquisition digital alignment of at least a pair of digital images of an object, the method comprising:
-
acquiring digital images of the object, stored as color matrices, through each of at least two lenses of substantially identical focal length, of substantially identical field of view and substantially identical image circle at a sensor plane of at least one sensor; each said lens being associated with a single or multi bandpass filter, such that each lens captures one light band similar to one light band captured by the other said lens and at least one light band different from the light bands captured by the other said lens; splitting the color matrix which was captured by the similar light band from the multi-band images acquired by the different lenses; and matching the substantially identical light band matrices from each lens for post-acquisition digital alignment of the images acquired by all the lenses. - View Dependent Claims (24, 25, 26)

31. A multispectral imaging apparatus comprising:
-
a mobile processing platform; at least two cameras integrated with the platform, each camera including a lens, at least one single or multi bandpass filter, and at least one sensor; and wherein the filters allow the passage of at least one visible and one non-visible band of light through the filters to the sensor; wherein the lenses are of substantially identical focal length, similar field of view and substantially similar image circle at a sensor plane. - View Dependent Claims (32, 33, 34, 35, 36, 37)
