Laser-fringe reference systems

In an interference optical system, coherent light from a laser is split into two beams. One is passed through the sample, and the other through the reference sector. The beams are then recombined and a pattern of fringes is created by constructive or destructive interference of the light waves. If one beam is slowed by higher refractivity of the sample, the fringe pattern will be shifted from a central reference position. This displacement is related to the sample concentration by... [Pg.489]
