Various kinds of optical systems are used for imaging purposes; this page gives a brief overview of what is covered in encyclopedia articles:

• Afocal optical systems are optical systems which output parallel rays for parallel input rays.
• Cameras are optical instruments for recording still or moving images. Specifically:
  • Infrared cameras are cameras which work with infrared light.
  • Photo cameras are optical instruments for taking photographic images.
• Hyperspectral imaging devices provide images with an optical spectrum corresponding to each pixel.
• Infrared viewers are instruments for observing scenes with infrared light.
• LIDAR devices can acquire 3D images with laser pulses.
• Microscopes are instruments for very small objects. Specifically:
  • Fluorescence microscopy equipment acquires microscopic images using fluorescence which is excited in the sample.
  • Laser microscopy systems generate microscopic images by scanning objects with a laser.
• Multispectral imaging devices provide images with multiple spectral channels.
• Night vision devices are instruments which allow viewing or imaging under conditions of very low light levels.
• Optical coherence tomography systems achieve longitudinal resolution based on interference effects with low-coherence light.
• Optical profilometers acquire high-resolution images revealing surface profiles.
• Spectral imaging devices provide images with spectral information.
• Telescopes are optical instruments for viewing distant objects.
• Thermal imaging cameras use long-wavelength thermal radiation.
