Abstract: One embodiment relates to an optical navigation device. The device includes a lead frame (102) having reference features, a laser (402), a detector array (404), and an optical component (106) having alignment features (206). The laser (402) is attached to the lead frame (102) and positioned in reference to the reference features (202) of the lead frame (102). The detector array (404) is attached to the lead frame (102) and positioned in reference to the reference features (202) of the lead frame. The optical component (106) is coupled to the lead frame (102) so that its alignment features (206) register to the reference features (202) of the lead frame (102). In this way, the molded optical component (106) is passively aligned to the laser (402) and the detector array (404). Other embodiments are also disclosed.

Abstract: One embodiment relates to a laser positioning device for sensing relative movement between a data input device and a surface (120) by determining displacement of image features in a succession of images of the surface. The device forms a single integrated package, which includes a planar substrate (102) and a transparent encapsulant that also embodies a collimating lens (108). Both a coherent light source (104) and a sensor array (106) and associated circuitry are configured on the planar substrate. Another embodiment relates to a method of sensing relative movement between a data input device and a surface. Coherent light is emitted from a laser and collimated so as to form a collimated illumination beam with a predetermined diameter, D, and a substantially uniform phase front. A speckle pattern is generated by impingement of the collimated illumination beam on the surface and detected by a sensor array. Other embodiments are also disclosed.
