Opto Engineering supports engineers in low-level programming with general purpose libraries (FabImage Library Suite) and specific, application-related libraries: TCLIB Suite, dedicated to setup and optimisation of telecentric systems (alignment of lens and light, alignment of object plane, focusing and distortion removal), and 360LIB Suite, developed to suit all needs of 360[degrees] lenses for single-camera inspection of cavities and lateral surfaces.
The variables represent the coordinates for elemental images and object plane images, some numbers for elemental images and object plane images, and physical information for a lens array and object planes.
In this method, called scanning SIM, illumination patterns are scanned onto the object plane. In that work, the authors use a TPE method with an intensity modulation that emulates a sinusoidal pattern in the object plane.
The focused objects were placed at a distance of 0.5m and 2m from the camera on the object plane in the experiments.
As shown in Figure 2(a), the original hyper-lens (the half- circular ring region of purple color) has a cylindrical object plane [S.sub.1] and a cylindrical image plane [S.sub.2].
The reference plane is perpendicular to the z-axis, and the object plane must appear on the right side of the reference plane.
The first transformation deals with propagating of waves from the object plane to the lens (in order to create synthetic datasets for testing).
This paper presents a generic method of calculating accurate horizontal and vertical object distances from digital images taken with any digital camera and lens combination, where the object plane is parallel to the image plane or tilted in the vertical plane.
All of the light entering the lenslets focuses into an array of points in the object plane of the objective lens.
