Light emitting sensor having a plurality of secondary lenses of a moveable control structure for controlling the passage of light between a plurality of light emitters and a primary lens

A light emitting sensor comprising:

• a primary lens;
• a plurality of individual light emitters arranged in an array, with the array of the individual light emitters arranged on a first plane;
• wherein each of the plurality of individual light emitters is operable to transmit a beam of light along a path that is perpendicular to the first plane;
• a control structure having a plurality of secondary lenses arranged in an array, with the array of secondary lenses arranged on a second plane disposed between the array of individual light emitters and the primary lens, with the first plane and the second plane parallel with each other;
• wherein each of the plurality of secondary lenses is a bi-telecentric lens;
• and
• an actuator coupled to the control structure and operable to move the control structure relative to the primary lens and the plurality of individual light emitters to control the passage of light between the plurality of light emitters and the primary lens.
