Abstract: Enhancing infrared measurement accuracy and thereby allowing remote diagnostics of various states that are characterized by minute temperature difference, beyond the capabilities of current infrared imaging systems is provided herein. Embodiments of the invention utilize the exact fusing of a visible light image and an infrared image, achieved by setting the system at a known spatial relationship in which they are both focused at the intersection of their optical axes, and identifying a well contrasting infrared region within a focused visible light image, to visually identify an uninfluenced target region that serves as a reference region for infrared temperature difference measurements. Using this reference allows enhancing the resolution of the infrared imaging by an order of magnitude.

Abstract: Optical systems and respective cameras are provided, which have a NUC (non-uniformity correction) -shutter incorporated internally in the optical system, between its optical elements. The NUC-shutter is configured to be temporarily inserted between two of the optical elements to enable performing NUC of a detector array in the camera. Camera designs, in particular infrared camera designs, achieve wide fields of view and very low distortions by exploiting the possibility to minimize the back focal length of the optical system which is enabled by the configuration of the NUC-shutter.

Abstract: Imaging system and method for detecting the presence of a substance that has a detectable signature in a known spectral band. The system comprises a thermal imaging sensor and optics, and two interchangeable band-pass uncooled filters located between the optics and the detector. A first filter transmits electromagnetic radiation in a first spectral band that includes the known spectral band and blocks electromagnetic radiation for other spectral bands. A second filter transmits only electromagnetic radiation in a second spectral band in which the substance has no detectable signature. The system also includes a processor for processing the images to obtain a reconstructed fused image involving using one or more transforms aimed at obtaining similarity between one or more images acquired with the first filter and one or more images acquired with the second filter before reconstructing the fused image.
