Abstract

Modulation of the frequency of a wave transmitted through an interference filter (1). The interference filter is mounted on adjustable ball-bearing (2) in ball-races which lie between the rollers (4) driven by a motor. The rollers are fixed to a wall (5) which can rotate above an adjustable shaft. This shaft can be used to adjust the angle of incidence and reflection. The filter is subject to rotation about an axis which makes an angle with the incident ray and with the normal to the surface of the filter. There is an inlet and an outlet opening to the housing for modulating the beam.
