The amount of power transferred between a source and a receiver depends on their areas, the distance separating them, and their mutual orientation. Boyd introduces the concept of , which is the product of the source area and the solid angle subtended by the receiver. Because throughput cannot be increased by passive optics, it sets a hard physical limit on the efficiency of optical systems and sensors.

Robert W. Boyd’s Radiometry and the Detection of Optical Radiation bridges the gap between abstract electromagnetic theory and practical experimental optics. For researchers, students, and engineers downloading or referencing this material, the text serves as a roadmap for: Because throughput cannot be increased by passive optics,
