Laser spectroscopy is a spectroscopic technique that uses lasers to be able determine the emitted frequencies of matter. [87] The laser was invented because spectroscopists took the concept of its predecessor, the maser, and applied it to the visible and infrared ranges of light. [87]

Raman had invented a type of spectrograph for detecting and measuring electromagnetic waves. [ 34 ] [ 78 ] Referring to the invention, Raman later remarked, "When I got my Nobel Prize, I had spent hardly 200 rupees on my equipment," [ 79 ] although it was obvious that his total expenditure for the entire experiment was much more than that.

Interest in theatrical 3D movies dwindled during the following decades, but they started to get exploited as (part of) special attractions, such as 4D simulator rides and Imax theatres. In the early 2000s, digital cinema began to takeover and polarized 3D movies became popular. Movies were no longer created on film.
