Projection system and method with dynamic target geometry

A method of driving a projection system, comprising:

• emitting a light by a light source, in response to an image data;
• receiving the light by a phase light modulator;
• applying a spatially-varying phase modulation on the light by the phase light modulator, thereby to steer the light and generate a projection light;
• dynamically determining, based on at least one of a user input or a sensor signal, a target geometry and a relief of a projection surface on which the projection light is projected;
• determining, based on the target geometry and the relief, a phase configuration for a frame of the image data by calculating a beam-steering drive solution for the phase light modulator based on the target geometry and relief that, when reconstructed, approximates the image data;
• and
• providing a phase control signal to the phase light modulator, the phase control signal configured to cause the phase light modulator to generate the projection light in accordance with the phase configuration for the frame.

A projection system, comprising:

• a light source configured to emit a light in response to an image data;
• a user-controlled input device configured to project a calibration code onto a user-selected projection surface;
• a phase light modulator configured to receive the light from the light source and to apply a spatially-varying phase modulation on the light, thereby to steer the light and generate a projection light;
• and
• a controller configured to:
• dynamically determine, based on at least one of a user input or a sensor signal, a target geometry and a relief of a projection surface on which the projection light is projected,
• determine, based on the target geometry and the relief, a phase configuration for a frame of the image data, and
• provide a phase control signal to the phase light modulator, the phase control signal configured to cause the phase light modulator to generate the projection light in accordance with the phase configuration for the frame.
