Abstract: Provided is a microscope provided with: a scanner that scans an excitation beam coming from a light source; an objective optical system that focuses the scanned excitation beam onto a sample and that collects fluorescence generated at individual scanning positions in the sample; a detector that detects the collected fluorescence; a light blocking member that is disposed between the detector and the system and that partially blocks the collected fluorescence; a switching portion that switches the positional relationship between the member and a light-focusing point of the excitation beam in the sample between an optically conjugate positional relationship, in which an in-focus fluorescence generated at the light-focusing point passes through the member, and a non-conjugate positional relationship, in which the in-focus fluorescence is blocked by the member; and a computing portion that computes a difference between fluorescence signals acquired by the detector in the two positional relationships.

Abstract: A photoacoustic imaging device includes an excitation light irradiation unit that irradiates the same position of a specimen with two or more beams of pulsed excitation light separated by an irradiation time interval, a detector that detects an acoustic wave generated at the position irradiated with the excitation light by the excitation light irradiation unit, a generator that generates an image of the specimen based on the detected acoustic wave, and a controller that controls the irradiation time interval, the acoustic wave generated with a single beam of pulsed excitation light has multiple positive peaks that periodically occur, and the controller controls the irradiation time interval into a timing at which a second positive peak of the acoustic wave generated with the preceding excitation light is superimposed on a first positive peak of the acoustic wave generated with the subsequent excitation light.

Abstract: A point-spread-function measurement device includes: a scanner that scans two illumination light beams emitted from a light source; an illumination optical system that radiates the two illumination light beams scanned by the scanner onto a sample; a relative-position adjustor that changes a relative irradiation position, in the sample, between the two illumination light beams radiated by the illumination optical system; a detection optical system that detects signal light generated at an overlapping position, in the sample, of the illumination light beams radiated by the illumination optical system; and a calculator that calculates a point spread function based on the signal light detected by the detection optical system and the relative irradiation position between the two illumination light beams when the signal light is detected.
