Abstract
A light sensor includes a primary lens, and a light device spaced from the primary lens. A control structure is disposed between the primary lens and the light device. An actuator is coupled to the control structure to move the control structure relative to the primary lens and the light device to control the passage of light between the primary lens and the light device. The light sensor may include a light emitting sensor having an array of individual light emitters, or a light detecting sensor having a light detector. The control structure may include an array of secondary bi-telecentric lenses for use with the light emitting sensor, or a plate having an aperture extending therethrough for use with the light detecting sensor.
