Abstract: A dual coating and lift-off method for protecting patterned dielectric-metal coatings using a 2-layer lithography process that is exposed and developed to create an undercut and then, after the wafer is coated with a metal/dielectric filter ending with an incomplete final layer, the top lithography layer is lifted off exposing metal layer edges and leaving the bottom lithography layer intact on the wafer such that the final filter layer(s) can be deposited to complete the coating and passivate the exposed metal layer edges is disclosed.

Abstract: This disclosure describes a method of improving filter wheel imaging data capture and other functionality through use of an improved filter wheel design with pie shaped filter segments, continuously rotating image capture, multiple filtered images, and easily removable and attachable filter segments.

Abstract: A new color wheel filter system for color changing lighting fixtures is disclosed. More specifically it is a method of improving the filter wheel functionality through use of an improved filter wheel design by maximizing the filter clear aperture by directly bonding the filter glass substrate to a small hub bearing and moving the drive belt to the outside diameter. The filter wheel can also be constructed to allow easy interchanging of layered filter wheels on the color changing lighting fixture.

Abstract: This disclosure describes an apparatus and method of multi-spectral imaging to obtain and analyze information contained in the spectral distribution (reflection, absorption, or emission) of components within the image. The spectral information is captured in a series of images from differing spectral regions. This series of images are then combined into a composite image using re-colorization and image stabilization algorithms for display in real time. The process can be repeated continuously allowing spectral changes over time to be captured and analyzed. In the alternative one sequence of images can be captured for use as a still image.
