The first reflector known dates from around 508 million years ago (Ma); the first eyes with lenses evolved at around 521 Ma. Consideration of the introduction of vision leads to a hypothesis for the cause of evolution's Big Bang—the Cambrian explosion.

On the origin of optics - ScienceDirect
WebThe first true optical fibers, invented in 1950, were thin rods or fibers of glass used in medicine to allow doctors to peer inside the body. In 1956 the term “ fiber optics ” was coined and research began on the use of optical fibers to transmit information. WebOptics is the physical science that studies the origin and propagation of light, how it changes, what effects it produces, and other phenomena associated with it. There are two branches of optics. Physical optics is concerned with the nature and properties of light itself. Geometrical optics deals with the principles governing image-forming ... WebNew applications for optical vortex interferometers (OVIs) are under investigation. The precision of the OVI depends strongly on the accuracy of positioning of the vortex points, which requires more than one interferogram (fringe pattern), so the influence of the laser beam's frequency stability is important. We present an analysis of the influence of the … call heart
