Title:
波面補正なく自由空間光信号を復調するためのシステムおよび方法
Document Type and Number:
Japanese Patent JP6985379
Kind Code:
B2
Abstract:
Optical signal receivers and methods are provided that include an optical resonator that allows an optical signal to enter and optical signal energy to accumulate at regions inside the optical resonator. A portion of optical signal energy is emitted from among various regions of the optical resonator, such that a combination of the emitted optical signal energy is disturbed when a phase transition occurs in the received optical signal. A detector aligned with the output detects the combined emitted optical signal energy and is configured to detect the disturbance and determine a characteristic of the phase transition in the received optical signal based upon the disturbance.
