An optoelectronic package for measuring distance, tip, and tilt of an object relative to a detector. The optoelectronic package comprises a carrier; a photodiode element (photodiode elements) located on the carrier and having a center opening; a vertical-cavity surface-emitting laser (VCSEL) located in the center opening and directing light rays toward the object; and an interference generating optical element positioned between the photodiode element and the object. Light passes through the optical element from the VCSEL creating a ring of measured light which reflects off the surface of the object and combines with a ring of reflecting reference light to produce interference fringes on the photodediode elements with varying light intensity, which correspond to displacement and angular tip and tilt of the surface of the object. The measurement of these variations will be interpreted by a computational element to produce a value of distance, tip, and tilt of the object.
