:Q．－144◇Q．－.

An interfermotetric technique used to create three-dimensional images. Often infrared light is used and scattered off of biological tissue to image the tissue with a resolution of up to a millionth of a meter. Better resolution can be achieved through proper selection of the light source. Interferometric techniques are ones that use the combination of light waves to obtain information about the light waves.

The ability of a substance to rotate the plane of linearly polarized light about the direction the light is traveling in, as the light travels through the substance. It often occurs in substances with molecules that have a mirror image structure, rotated crystal planes, and gases that have their molecular spins polarized (aligned in a particular direction).

1620, originally in the philosophical sense of "considered in relation to its object" (opposite of subjective), formed on pattern of M.L. objectivus, from objectum "object." The lens or lens system in a microscope or other optical instrument that first receives light rays from the object and forms the image.

A projector used to project transparencies. This type of projector usually consists of a large box with bright lamps and a fan, above which is a Fresnel lens that acts to collimate the light and acts as a platform for placing the transparencies. The transparencies can be written and projected onto a wall by utilizing a 45° mirror and lens system above that turns the vertical beam from the lamps below into a horizontal direction. The image is usually projected onto a screen. This allows a speaker to face the audience and utilize normal writing on the transparency, and an erect and magnified image appears on the screen for the audience.

1658, from Fr. oscillation, from L. oscillationem (nom. oscillatio), pp. of oscillare "to swing," supposed to be from oscillum "little face," lit. "little mouth," a mask of open-mouthed Bacchus hung up in vineyards to swing in the breeze.

A branch of physics that studies electromagnetic radiation (for example, light and infrared radiation), its interactions with matter, and instruments used to gather information due to these interactions. Optics includes the study of sight.

1541, from M.Fr. optique, obtique (c.1300), from M.L. opticus "of sight or seeing," from Gk. optikos "of or having to do with sight," from optos "seen, visible," from op-, root of opsesthai "be going to see," related to ops "eye," from PIE *oqw- "eye/see" (see eye). Optics "science of sight and light" is from 1579; optician is first attested 1687, after Fr. opticien.
