Abstract
A system, method, and apparatus for sensing an operational condition of a projection device and generating a signal to be used in the adjustment of the relative disposition of a component of the projection device, are disclosed herein.
Claims30
An apparatus comprising:
- a light valve adapted to output a first image;
- projection optics optically coupled to the light valve to project the first image, the projection optics having a first lens element relatively disposed away from the light valve;
- and
- a sensor, adapted to sense a condition, and to generate a first signal based at least in part upon the sensed condition, for use to adjust the relative disposition of the first lens element and the light valve.

A method comprising:
- operating a light valve to output a first image;
- projecting the first image with projection optics having a first lens element relatively disposed away from the light valve;
- sensing a condition;
- and
- generating a first signal based at least in part upon the sensed condition, for use to adjust the relative disposition of the first lens element and the light valve.

A system comprising:
- a light source to provide light;
- a light valve optically coupled to the light source to receive the light and to output a first image;
- projection optics optically coupled to the light valve to project the first image, the projection optics having a first lens element relatively disposed away from the light valve;
- and
- a sensor, adapted to sense a condition, and to generate a first signal based at least in part on the sensed condition, for use to adjust the relative disposition of the first lens element and the light valve.
