Ophthalmic imaging is a specialized form of medical imaging dedicated to studying and treating eye disorders. Ophthalmic diagnostic imaging integrates science and art to provide images to record the progress of treatment and for research and teaching purposes in ophthalmology.
Since the 1930’s, mean skin temperature has been routinely measured through the use of thermistors, thermocouples, and thermocrons that are often attached to the skin directly.

Optical resolution is the physical resolution at which an imaging device can capture an image. The term is mostly used in connection to optical scanners and digital cameras.
A pinhole camera, also known as camera obscura or "dark chamber", is a simple camera that has a single small aperture called pinhole instead of a lens. The concept of pinhole camera was published in the Book of Optics in 1021 AD by Persian scientist Ibn al-Haytham.
Magnifying power is defined as the ratio between the dimensions of the image and the object. The process of magnification can occur in lenses, telescopes, microscopes and even in slide projectors. Simple magnifying lenses are biconvex - these lenses are thicker at the center than at the edges.
The CCD (charge coupled device) was first invented at the Bell laboratories in the 1960s. CCDs are thin wafers which consist of a number of buried electrodes that facilitate the movement of electrons from the device to a desired point.
