microlens arrays custom

US7687757B1

A method for designing a microlens array on a pixel array is disclosed. A radial distance of each pixel from a central pixel in a pixel array is calculated, in which the central pixel acts as an origin of an X-Y coordinate. A chief ray angle of each pixel is determined according to the corresponding radial distance. A microlens shift with respect to the corresponding pixel is determined Get price

How to create an array of custom type in C#?

Yeah, that is a nice way to do it. I already discussed in StackOverflow and found that I can't access the fields of class like an array. What I gave here is short form of it. And people in last discussion suggested to use array so can access the fields of classes with indexes. – Vikyboss Jul 20 '11 at 19:56 Get price
