Optical platform comprising multiple optical projectors

1 . An optical platform configured to project image onto a target, wherein the optical platform comprises a plurality of optical projectors, each configured to project an image that covers the whole field of view onto said target, wherein each of the plurality of optical projectors is associated with a controllable switch which is configured to enable or disable operation of a respective optical projector from among said plurality of optical projectors, thereby enabling switching between operative optical projectors while said optical platform remains operative and wherein the switching of optical projectors is carried out within a single time frame, being an exposure time window, by switching off any one or more optical projectors from among the plurality of optical projectors comprised in said optical platform which are operative within a first part of a time frame, and switching on any one or more currently non-operating optical projectors from among the plurality of optical projectors comprised in said optical platform, to operate within a second part of said time frame.

2 . The optical platform of claim 1 , wherein images projected at at least some of the time frames are projected by a single optical projector from among the plurality of optical projectors.

3 . The optical platform of claim 1 , wherein images projected at at least some of the time frames, are projected by at least two of the plurality of optical projectors that are operative simultaneously, wherein each of the operative optical projectors, projects an image at each of said at least some of the time frames.

4 . The optical platform of claim 1 , wherein at least two of the plurality of optical projectors are operative simultaneously at any given time during operation of said optical platform.

5 . The optical platform of claim 1 , wherein said plurality of projectors are driven in series by a controlled current source.

6 . The optical platform of claim 1 , wherein each of said plurality of projectors is associated with a bypass controllable switch.

7 . The optical platform of claim 1 , further configured to switch between optical projectors that project images comprised in two consecutive time frames from among the plurality of time frames.

8 . The optical platform of claim 7 , wherein in a case that the switching of optical projectors is carried out between two consecutive time frames, by switching off a single optical projector operative for projecting an image within a first time frame from among the plurality of time frames, and switching on at least two of the plurality of optical projectors, for projecting an image within a second, consecutive time frame.

9 . The optical platform of claim 1 , wherein at least two of the optical projectors operating simultaneously, are configured each to project the same or a different pattern than another of the plurality of optical projectors.
