Abstract
An optical measurement device includes: an optical sensor that detects pulsed signal light and that outputs a detection signal formed of an exponential-function response; an A/D converter that samples the detection signal output from the optical sensor and that converts the detection signal into a digital signal; and a processor comprising hardware, the processor being configured to subject the digital signal output from the A/D converter to inverse transformation by using a multiple diagonal matrix, thus calculating an estimated pulse of the signal light.
Claims19
A scanning microscope comprising:
- a scanner that scans, on a sample, illumination light emitted from a light source;
- an optical system that focuses, on the sample, the illumination light scanned by the scanner and that collects signal light generated at each scanning position in the sample, at which the illumination light is scanned;
- an optical measurement device that calculates an estimated pulse of the signal light collected by the optical system;
- and
- an image reconstruction unit that reconstructs an image of the sample on a basis of the estimated pulse calculated by the optical measurement device,
- the optical measurement device comprising:
- an optical sensor that detects pulsed signal light and that outputs a detection signal formed of an exponential-function response;
- an A/D converter that samples the detection signal output from the optical sensor and that converts the detection signal into a digital signal;
- and
- a processor comprising hardware, the processor being configured to subject the digital signal output from the A/D converter to inverse transformation by using a multiple diagonal matrix, thus calculating the estimated pulse of the signal light.
