G&H engineered Polarization Diverse Receiver delivers OCT Systems Innovation 09 Apr 2021 At G&H we understand our customers’ need for high performance, as well as flexibility in design, and we have invested in R&D and listened to our customers’ needs to develop key components such as our highly compact Polarization Diverse Receiver (PDR) A PDR interferes the two incoming beams and splits them into their orthogonal linear polarization states for high speed, polarization-sensitive OCT measurements. Depending on the application area, three types of PDR are each specified to operate at different wavelengths: 1550 nm for industrial applications 1310 nm for cardiology and skin cancer applications
