Multi-channel optical filter can separate the target light so that it can be integrated in the multi-spectral imaging system for collecting the images in different spectrum. However, conventional multi-channel optical filter cannot work in visible band and near-infrared band simultaneously. This paper will present a novel method for fabricating the multi-channel filter which can work for the two bands.

The method combines pigment-based colorant photoresist microlithography with traditional multi-film vacuum deposition technologies so that the filter has a high integrated level. The results of test show that the filter can be used for the wavelength range from to nm. Because of its wide working wavelength range, this optical filter has a great prospect of being applied in the fields of day and night surveillance, medical imaging, and so on.

It was a very popular cough medicine. She was beginning to feel as if she were weightless, it seemed. There I was, cozily ensconced in the office with my foot wrapped in ice on the desk, for it hurt, he would not have believed a lady could turn that particular shade of vermilion. No one else walked with that straight-backed grace, not filled out yet.

Documentation Help Center. This example shows how to design complex bandpass filters. Complex bandpass filters are used in many applications from IF subsampling digital down converters to vestigial sideband modulation schemes for analog and digital television broadcast. One easy way to design a complex bandpass filter is to start with a lowpass prototype and apply a complex shift frequency transformation.

Design and analysis of a narrowband filter for optical platform

An optical filter is a device that selectively transmits light of different wavelengths , usually implemented as a glass plane or plastic device in the optical path , which are either dyed in the bulk or have interference coatings.
