Abstract: A signal detection circuit includes: a VCO that generates a reference signal; a complex signal generation circuit that generates a complex signal from an input signal and the reference signal; a vector operation circuit that calculates an argument of the complex signal by performing a vector operation; and a subtracting phase comparator that compares the argument with a phase of the reference signal by calculating a difference between the argument and the phase of the reference signal, wherein the complex signal generation circuit includes: a multiplication circuit that multiplies the input signal by the reference signal; and an HPF that removes a DC component from a signal output from the multiplication circuit.

Abstract: Provided is a sealed AFM cell in which measurement accuracy does not decrease and the types of observation liquids are not limited. A sealed AFM cell according to the present invention includes: a cantilever including a probe; a sample holder for fixing the sample; a scanner for moving the sample holder; a lid part which holds the cantilever so as to position the probe near a measurement surface of the sample; and a main body part which is a component for holding the scanner and positioned opposite the lid part with the sample in between, in which the lid part and the main body part are joined via a sealing liquid to seal the observation liquid inside a space formed by the lid part, the main body part, and the sealing liquid, the sealing liquid being different from the observation liquid and not in contact with the observation liquid.
