    摘要： An optical coherence tomography, OCT, adapter (206) configured to be under-mounted to a microscope (200), the OCT adapter (206) comprising: a housing (208) configured with a mounting mechanism for engaging with an under-carriage of the microscope (200) and a plurality of optical components (210, 310, 330, 316, 318) contained in the housing (200), wherein at least the plurality of optical components defining an optical path for a OCT probe beam (312) which emerges from the housing collinear with an optical channel of the microscope, wherein the optical components are configured such that the housing (208) of the OCT adapter (206), when fixed to an undercarriage of the microscope (200), increases a height, h2, of the microscope by less than 40mm.

    摘要： A signal processing device includes a controller which acquires an output signal output from a single light receiver that receives a plurality of interference beams in which a light beam that is output from a single light source and traces a sample arm toward a measurement target and a light beam that is output from the light source and traces a reference arm that is different from the sample arm interfere with each other, the plurality of interference beams each having a different wavelength dispersion characteristic difference between the sample arm and the reference arm traced by the light beams interfering with each other; and extracts an extraction signal that is a signal for each of the interference beams on the basis of the output signal acquired and a correction signal obtained by applying wavelength dispersion correction processing to the output signal.
