Final answer:
In a CR reader, a beam splitter is used to redirect some of the laser light to a reference detector, which is common in precision applications like biomedical imaging systems.
Step-by-step explanation:
In the context of a CR reader, some of the laser light is redirected to a reference detector by way of a beam splitter. Beam splitters are optical devices that divide a beam of light into two separate paths. One path is typically used for the working process, such as reading information from a surface, while the other path is directed towards a reference or monitoring detector. This process is crucial for applications such as biomedical imaging systems, where precision and accuracy in light detection are paramount for creating high-quality images from detector outputs.
