INTENSITY NOISE REDUCTION METHOD AND APPARATUS FOR INTERFERENCE SENSING AND IMAGE CAPTURE SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a method, an apparatus and a system for intensity and/or pattern line noise reduction in a data collection system such as an optical coherence tomography system.;SOLUTION: The optical coherence tomography system includes: a first photoreceiver P1 for receiving light from an interferometer that performs optical communication with a laser and electrical communication with a first resister R1; a first attenuator 12 configured to change either a first optical or a first electrical property of the first attenuator in response to a first control signal; a second photoreceiver P2 for performing electrical communication with a second resistor; a second attenuator configured to change either a second optical property or a second electrical property of the second attenuator in response to a second control signal; an amplifier 14 having first input and first output for performing electrical communication at the first resistor and second resistor; and a feedback network configured to generate a first control signal and a second control signal in response to a laser intensity noise component.;COPYRIGHT: (C)2015,JPO&INPIT
