A system, apparatus and method for three-dimensional scanning and digitization of the surface geometry of objects are claimed. The system comprises a hand-held apparatus that is auto-referenced. The system is auto-referenced since it does not need any positioning device to provide the 6 degree of freedom transformations that are necessary to integrate 3D measurements in a global coordinate system while the apparatus is manipulated to scan the surface. The system continuously calculates its own position and orientation from the reflection of a projected laser pattern on an object's surface and 2D positioning features originating from the observation of target positioning features. Using the described system, it is possible to simultaneously build and match a 3D representation of the positioning features while accumulating the 3D surface points describing the surface geometry.

A enhanced abradable friable graded insulator FGI results from the laser patterning of a coating where a series of top surfaces reside on a series of columns such that the walls of the columns are not significantly densified relative to the interior of the columns. Patterns can be generated where the columns are oriented independently normal to or at an acute angle to the top surfaces. The cross sections of the top surfaces are formed to conform to the average dimensions of the spheres of the FGI coating. The cross sections of the top surfaces can be more than 1.5 times the diameter of the spheres. Various patterns of top surfaces can be used including regular, random, quasiperiodic patterns. A gradient of abradability can be imposed on the coating.

This invention contemplates the use of laser patterning/scribing in electrochromic device manufacture, anywhere during the manufacturing process as deemed appropriate and necessary for electrochromic device manufacturability, yield and functionality, while integrating the laser scribing so as to ensure the active layers of the device are protected to ensure long term reliability. It is envisaged that the laser is used to pattern the component layers of electrochromic devices by directly removing (ablating) the material of the component layers. The invention includes a manufacturing method for an electrochromic device comprising one or more focused laser patterning steps. To minimize redeposition of laser ablated material and particulate formation on device surfaces a number of approaches may be used: (1) ablated material generated by the focused laser patterning may be removed by vacuum suction and/or application of an inert gas jet in the vicinity of the laser ablation of device material; (2) spatial separation of the edges of layers and patterning of lower layers prior to deposition of upper layers; and (3) the laser patterning step may be performed by a laser beam focused directly on the deposited layers from above, by a laser beam directed through the transparent substrate, or by a combination of both.

Thin film batteries (TFB) are fabricated by a process which eliminates and/or minimizes the use of shadow masks. A selective laser ablation process, where the laser patterning process removes a layer or stack of layers while leaving layer(s) below intact, is used to meet certain or all of the patterning requirements. For die patterning from the substrate side, where the laser beam passes through the substrate before reaching the deposited layers, a die patterning assistance layer, such as an amorphous silicon layer or a microcrystalline silicon layer, may be used to achieve thermal stress mismatch induced laser ablation, which greatly reduces the laser energy required to remove material.

For electrically non-conductive substrates, cathode contact areas are opened-up through the substrate.
