The "eyes" that enable us to see the particle beams are called Beam Position Monitors. BPM design is based on detection of electric fields of the bunches passing through electrodes located inside the vacuum chamber. The weak electric signals are filtered, amplified and digitized to provide us with the orbit data. The progress with advancing the BPM accuracy, sensitivity, speed and data volume has escalated manyfold in the last few decades following the rapid growth of capabilities of the modern electronics. In my presentation I will go over the basic principles, the history and the future prospects of BPM diagnostics for particle accelerators. Concurrently I will introduce our home-grown solution for NSLS-II RF BPMs and present the accomplishments to date, experience from operations and studies and an outlook at the future developments in both Analog and Digital domains of our devices.
