Experiments
Introduction
Classification
Time-multiplexing
Spatial codification
Direct codification
Direct codification: grey levels
• Every encoded point of the pattern is
identified by its intensity level
Carrihill and Hummel Intensity
Ratio Sensor: fade from black to white
Requirements to obtain
high resolution
Every
slit is identified by its own intensity
• Every slit must be projected using a single
wave-length
• Cameras
with large depth-per-pixel (about 11 bits) must be used
in order to differentiate all the projected intensities
Conclusions
