چکیده
This paper describes technical/mathematical solutions for simulating infra-red sensor e ects. We have implemented our simulation using a pc running Windows nt and o -the-shelf image processing hardware and software. In particular, we describe the computation of the dynamic characteristics of the actual sensor package within the constraints of hardware and software environment. These characteristics can include video polarity, gain, contrast enhancement, noise, blurring, AC coupling, sensor defects, as well as video overlays (reticules/test patterns), and are applied in the post-processor phase. This paper describes the research and development into the Infra-Red Post Processor (irpp) algorithms needed to support the sensor simulation. The system performs all the operations in real-time with a 30 Hz refresh cycle. The irpp is modular and can be easily changed by con guration data. Sanjiv K.

Advancements in infra-red array detectors
Despite many advances during the last decade in both infra-red sensor and solid state camera technology, until now little headway has been made in the production of cost-effective semiconductor sensor arrays capable of operating far into the infra-red. Old ideas, renewed by the capabilities offered by the latest micromachine technology, may change all this. Reviews the problems associated with ...
متن کاملSpectral Characterization of a Prototype SFA Camera for Joint Visible and NIR Acquisition
Multispectral acquisition improves machine vision since it permits capturing more information on object surface properties than color imaging. The concept of spectral filter arrays has been developed recently and allows multispectral single shot acquisition with a compact camera design. Due to filter manufacturing difficulties, there was, up to recently, no system available for a large span of ...
