Medical optical imaging is the use of light as an investigational imaging technique for medical applications, pioneered by American Physical Chemist Britton Chance. Examples include optical microscopy , spectroscopy , endoscopy , scanning laser ophthalmoscopy , laser Doppler imaging , optical coherence tomography , and transdermal optical imaging .
The most famous compound optical instruments in science are the microscope and the telescope which were both invented by the Dutch in the late 16th century. [110] Microscopes were first developed with just two lenses: an objective lens and an eyepiece. The objective lens is essentially a magnifying glass and was designed with a very small focal ...

In optics, an image-forming optical system is a system capable of being used for imaging. The diameter of the aperture of the main objective is a common criterion for comparison among optical systems, such as large telescopes. The two traditional optical systems are mirror-systems and lens-systems .
