Area of Science:

Optics
Display Technology
Acousto-Optics

Background:

Acousto-optic deflection in laser color TV systems suffers from optical dispersion, affecting deflection angles.
Smaller deflection angles for blue and green primary images lead to convergence issues in full-color displays.

Purpose of the Study:

To overcome optical dispersion in acousto-optic deflection for laser color TV systems.
To achieve accurate convergence of primary images across the entire TV raster.

Main Methods:

Utilizing prisms to magnify smaller deflection angles of blue and green primary images.
Employing a cascade of two prisms to achieve deflection angle-invariant magnification.
Implementing acousto-optic intensity modulation and horizontal scanning for a full-color TV projection system.

Main Results:

Successfully magnified smaller deflection angles, correcting for optical dispersion.
Achieved deflection angle-invariant magnification using cascaded prisms.
Demonstrated convergence of three primary images across the entire TV raster.

Conclusions:

Prism magnification effectively overcomes optical dispersion in acousto-optic deflection systems.
The proposed system enables accurate image convergence for full-color laser TV projection.
Acousto-optic modulation combined with prism optics provides a viable solution for advanced display technologies.
