Abstract
The ultra-weak photon emission is an intrinsic and spontaneous process in biological objects without any external excitation and is referred to as "biophoton emission". This paper reports the design of the rotation ellipsoidal cavity that was used in detecting ultra-weak photon emission from biological objects. The cavity can assemble the photons from biological sample at one focal plane of the rotation ellipsoidal cavity to the photomultiplier tube at another. The paper discusses the mathematical model of the cavity and the efficiency of collecting photons with the cavity. The measuring results for biological sample are given. The results are shown that the efficiency of collecting photons for the system with the cavity is evidently raised.
