Refractive Dual Band Infrared Imager Optical Design

Infrared imagers are important for reorganization and monitoring. This paper discusses the design of an infrared imager. Optical design in medium wavelength infrared (MWIR) and long wavelength infrared (LWIR) bands is different and needs distinct detectors and materials. Reflective systems are not suitable due to their small field of view (FOV) and vignetting. Refractive dual band optical syste...

Application of narrow band-gap materials in nanoscale spin filters

We develop a simple analytical model to study the influence of different material systems on the operation of a quantum-point-contact spin filter. Such a device has been predicted to allow for local control of the spin polarization in a semiconductor, and for direct electrical detection of the induced spin polarization. Narrow band-gap semiconductors, such as InAs and InSb, are predicted to exh...

Characterization of Narrow Band Filters for

We present a characterization of two narrow band lters commonly used in Infrared Astronomy. Our study mainly quantiies the eeect of temperature and tilt angle on the central wavelength and width of the transmission bands of such lters. This allows to evaluate some important eeects that must be taken into account to have good quality astronomical images. EEects as the limitation of the eld of vi...

Efficient Multirate Realization for Narrow Transition-Band FIR Filters

A filtering technique for reducing the computational complexity in FIR 5lters a t any bandwidth is advanced. This technique uses a combination of multirate and complementary filters. It is shown tha t the resulting computational complexity is almost independent of the transition bandwidth of the filter, but depends somewhat on the cut-off frequency.

A Novel Implementation for Narrow-Band FIR Digital Filters

In the cascade realization of fixed-point digital filters underdynamic range constraints, the output noise due to accumulation ofroundoff errors is highly dependent upon the order of the sections.For recursive filters it also depends on the pole—zero pairing that formsthe individual second-order sections. The output noise may vary overseveral orders of magnitude for differen...
