Multispectral Imaging Techniques

  • Ravi P. Gupta


In this chapter we discuss the principle of non-photographic multispectral imaging systems. A digital sensor comprises of a detector part and an optical part. Various types of photo conductive detectors are used for quantifying the radiation intensity. Resolution of a sensor is considered in terms of spatial resolution, spectral resolution, radiometric resolution and temporal resolution. Important types of scanners or imaging devices include: the opto-mechanical line scanner, CCD-line scanner and digital cameras. The focal plane arrays and time-delay integration architecture of CCD linear arrays has added a new dimension to the remote sensing imaging capability.
