Multispectralimage

One can realize spectral scanning by adding a multispectral wheel to a conventional camera with a broadband response. Such a wheel contains multiple optical bandpass filters for selecting different wavelength regions. The wheel may be continuously rotating, or alternatively one may randomly select one filter at a time with computer control. This technical approach has the advantage that one can easily choose from a variety of filters, depending on the specific application.

Multispectralcamera uses

A mixed approach is to use common optics for all wavelengths, but to separate the different wavelengths channels before sending the light to several image sensors.

One may employ a combination of cameras, for example one for visible light (with 3 or 4 channels) and one or more infrared cameras. Each of the cameras may be equipped with bandpass filters for limiting the sensitivity to a certain spectral region. Each optical system can then be optimized for the relevant spectral region, and less specialized image sensors are required. Disadvantages are that one requires multiple camera objectives and needs to ensure good spatial overlap of the obtained images (which is most difficult for near objects).

For a limited number of wavelength channels (e.g. 5 or 8), one may use a kind of image sensor which for each pixel has multiple photodetectors, one for each wavelength channel – similar to an RGB sensor as used in a photo camera. While this operation principle leads to a simple optical setup, it has some limitations:

Definition noun (general) The condition of polarity (biology) The process or act of producing positive and negative electric charge values to opposite ends, such as the electrical charge inside a (nerve) cell relative to the surrounding environment Supplement Polarization in general context refers to the state or condition of polarity. In biology, polarization pertains to the act or process of producing a positive electrical charge and a negative electrical charge such that between a nerve cell internal electrical charge, which is negative, and the surrounding environment of a nerve cell, which is positive. The cell is able to regulate the differing electrical charge relative to its surrounding via the plasma membrane. A closer look at the plasma membrane reveals transmembrane proteins and pumps that act as ion channels. These proteins that are embedded in the plasma membrane are selective, which means they allow certain molecules to move in and out of the cell while prevent or control the efflux and influx of others (in this regard, ions). There are move negative ions (e.g. Cl–) inside the cell, which results in a cell that is negative relative to the outside. In general, a nerve cell has a resting potential of approximately -70 mV.1 Word origin: French polarisation Variant(s):

The principle of line scanning is often used with instruments in moving objects such as airplanes and satellites; it is sufficient to subsequently make recordings for one line perpendicular to the flight direction, and to assemble those to obtain complete images, which can cover large elongated areas. Similarly, stationary scanning instruments are used for inspecting objects on conveyor belts in industrial factories.

One can also employ the principle of scanning imagers, which is most often realized for hyperspectral imaging. The most common method is to select only image information along a line, using an optical slit in an image plane, and to disperse the different wavelength components in the direction perpendicular to that line. A complete image needs to be assembled by combining recordings for different orientations of the camera, the slit or the object. One may not necessarily assign one spectral bin to each pixel in the direction of spectral dispersion, but combine multiple pixel according to the required spectral channels.

In principle, one might also consider color photography as means for multispectral imaging, but multispectral imagers typically offer non-overlapping wavelength channels, and also typically more than three channels.

One may alternatively use point scanning, which has the advantage that one can use a simple kind of spectrometer, for example an acousto-optic tunable filter. However, this leads to tentatively longer acquisition times and stronger motion artifacts.

Multispectral imaging means methods for spectral imaging where one obtains images corresponding to at least a couple of spectral channels – sometimes more than ten. The used spectral regions are often at least partially outside the visible spectral range, covering parts of the infrared and ultraviolet region. For example, a multi-spectral imager may provide wavelength channels for near-UV, red, green, blue, near-infrared, mid-infrared and far-infrared light – sometimes even thermal radiation (→ thermal imaging).
