Title:
A system and a method of controlling an optical interference tomogram
Document Type and Number:
Japanese Patent JP6272868
Kind Code:
B2
Abstract:
The invention relates to an optical coherence tomography system (5) comprising: a swept light source (7) comprising a tunable filter (9) comprising an input, the tunable filter (9) in optical communication with a sample arm (21) of an interferometer (18), wherein the tunable filter (9) is drivable bidirectionally and has an asymmetric sweep response; a control system (15) comprising a non-transitory memory and an output, wherein the output is in electrical communication (12) with the input, the control system (15) configured to drive the tunable filter (9) in one or more directions; and a drive waveform (10) stored in the non-transitory memory, the drive waveform (10) configured to cause a sweep response in a forward scan direction of the light source (7) and a sweep response in a backward scan direction of the swept light source (7) to be substantially symmetric and substantially linearize a sweep response of the light source (7), wherein an effective duty cycle of the swept light source (7) is greater than about 90% of a sweep period of the swept light source (7) when collecting optical coherence tomography data.
