[IDEA] random modulation

In the paper Modulated Phase-Shifting, we have problem with really high frequency pattern to be projected. I means the Morrie-like pattern.

How about using random modulation?
Modulate the pattern with random pattern and its complementary.

The idea is from dithering.


spatial and temporal dithering for direct/global component separation and 3D scanning of translucent objects

frequency analysis (projected onto a diffuse white/gray screen)

ｄｉｔｈｅｒｉｎｇ　ｃａｌｉｂｒａｔｉｏｎ

High speed camera

DLP　ｐｒｏｊｅｃｔｏｒ

How to conquer these two problems?
- finite resolution of the camera and projector
- narrow depth of field of the projector

A future avenue of research is to design 2D spatial intensity patterns that create temporal dithering codes that are optimal for the task at hand.
