Modtager = receiver. Prøve = sample.
An beam is emitted from the emitter send to the beam splitter and is devided into two as shown in the figure. From the sample (prøve) the beam is reflected and now send back to the beamsplitter.
I mesure that the reflected beam reaches the receiver, question is how. I have come to the conclusion that b1 must be a mirror for the reflection of the sample to reach the receiver. Is this true? ¨
