Abstract
An optical assembly for illuminating at least one object appearing in a field of view (FOV). The optical assembly includes first and second illumination sources configured to provide first and second illumination to illuminate a target of the object. An aperture configured to collimate the first and second illumination and to provide the illumination to a dual collimator. The dual collimator is disposed to collimate the first and second illumination and to provide the first and second illumination to a dual microlens lens array (MLA). The dual MLA has microlens arrays configured to receive the collimated first and second radiation, to provide two illumination output fields, each output field having a different output illumination field angle.
