Abstract
A method for imaging includes capturing images of an object using a matrix of detector elements and performing a processing operation in the detector elements under control of a global clock. Results of the processing operation are read out under control of a rolling clock, which is unsynchronized with the global clock.
Claims21
A method for imaging, comprising:
- capturing images of an object using a matrix of detector elements;
- performing a processing operation in the detector elements under control of a global clock;
- and
- reading out results of the processing operation under control of a rolling clock, which is unsynchronized with the global clock.
1 more element
Apparatus for imaging, comprising:
- a matrix of detector elements, which is configured to capture images of an object;
- embedded processing circuitry, which is configured to perform a processing operation in the detector elements under control of a global clock;
- and
- a readout circuit, which is configured to read out results of the processing operation under control of a rolling clock, which is unsynchronized with the global clock.
1 more element
Projection apparatus, comprising:
- a radiation source, which is configured to generate an illumination beam;
- scanning optics, which are configured to scan the illumination beam along a first axis;
- a control circuit, which is coupled to modulate the illumination beam while the beam is scanned;
- and
- a cylindrical optical element, which is configured to generate one or more spatial patterns by spreading the modulated beam along a second axis, perpendicular to the first axis.
2 more elements
Projection apparatus, comprising:
- a patterned element comprising multiple areas, which when illuminated, create different, respective spatial patterns;
- and
- at least one radiation source, which is configured to illuminate the areas sequentially so as to project the spatial patterns in a temporal sequence.
