Optical window design for MWIR camera

Appropriate energy window width for gamma camera [Persian]

Introduction: Scatter radiation is one of the major sources of error in nuclear medicine data processing. Different methods of scatter correction have been introduced in order to improve the quality of data. However the best method is to avoid recording of scatter photons in acquisition. The only difference between scattered and non-scattered photons is the energy. Pulse height analyzer i...

Virtual camera calibration using optical design software.

Camera calibration is a critical step in many vision applications. It is a delicate and complex process that is highly sensitive to environmental conditions. This paper presents a novel virtual calibration technique that can be used to study the impact of various factors on the calibration parameters. To highlight the possibilities of the method, the calibration parameters' behavior has been st...

Natural optical design concepts for highly miniaturized camera systems

Microcameras for computers, mobile phones, watches, security systems and credit cards is a very promising future market. Semiconductor industry is now able to integrate light reception, signal amplification and processing in a low-powerconsuming microchip of a few mm2 size. Active pixel sensors (APS) supply each pixel in an image sensor with an individually programmable functionality.[ I ] Besi...
