Abstract: A system and method are provided to rapidly inspect Liquid Crystal On Silicon (i.e., LCOS) displays to identify non-uniform cell gaps. The system includes a light source, a single polarized optical filter, and a color camera. The image acquired by the camera is analyzed to find variations in color. Excessive variations in color are used to identify excessive variations in the cell gap of the LCOS display. The arrangement of the components of the system does not require great precision and the analysis can be done very quickly.

Abstract: A method, a system and a computer-readable storage medium having stored therein a program for interactively developing a graphical control-flow structure and associated application software for use in a machine vision system is provided. The structure is a tree view structure including a control sequence having at least one node. The method includes providing a first set of control programs representing possible machine vision tasks. The first set of control programs defines a first set of standard controls. Hardware operating parameters are provided which correspond to possible hardware. The hardware operating parameters defining a second set of standard controls. Graphical representations of possible hardware and possible machine vision tasks are displayed. Commands are received from a user to select desired hardware operating parameters corresponding to desired hardware and a machine vision graphical representation and its associated first control program corresponding to a desired machine vision task.
