Star limits (starfield) projection device

摘要

Being the projection device which creates with the cloud condition effect which is moved with the star limits which it moves, it supplies and manages the expedient which creates the star limits which it moves the expedient which creates the cloud condition effect making use of one non coherent illuminant at least and, making use of one coherent illuminant at least and, and, it is the device which possesses with the expedient which electric power and. At least, the expedient which creates the cloud condition effect making use of one non coherent illuminant has with the interference filter wheel which at least turns with the convergent lens and the motor of 1 pair, the particular wheel is arranged at least between the convergent lenses of 1 pair. The expedient which creates the star limits which are moved making use of the coherent illuminant has with the diffraction optical element which is arranged the grating wheel and at least with of one coherent illuminant and the grating wheel which turn with the motor.
