1. A sample observation apparatus comprising:

  • an excitation light irradiation unit to irradiate a sample with an excitation light;

    an excitation light modulation unit to modulate a spatial intensity distribution of the excitation light on the sample;

    an excitation light modulation control unit to control the excitation light modulation unit according to a modulation control signal;

    a photo detection unit to detect light emission from the sample caused by irradiation with the excitation light to generate a detection signal;

    an image generation unit to generate image data of the sample according to the modulation control signal and the detection signal;

    a modulation control signal generation unit to generate the modulation control signal such that a Nyquist frequency of the image data will be larger than a cut-off frequency in the spatial intensity distribution of the excitation light on the sample; and

    an image processing unit to emphasize a high-frequency component that exceeds the cut-off frequency included in the image data.
