All that needed to be added was a few specially designed and custom made plastic pieces. They needed to create a bed of scanning samples that could move back and forth in one direction while the laser itself swung back and forth in the other.
Unlike an optical microscope, in which an entire image of an object is acquired at once, a scanning laser microscope measures the intensity of light in chunks by moving a grid over the object and collecting a pixel-by-pixel magnified image. In this case, given the limitations of the Blu-Ray drive spindle moving the displayed sample back and forth, the image is collected from 16,129 dimensions (127×127 grid) and then scaled to a 512×512 image.
The user interface allows you to adjust the focus and scanning speed of the microscope.
