Abstract: An interference image acquisition apparatus includes a light source, a beam splitter, a second reflection mirror, an imager, and a first reflection mirror. A cell is placed on one side of a transparent material, and the first reflection mirror is placed on the other side of the transparent material. In a two-beam interferometer, an optical path difference between an optical path length of a first light beam reflected by the first reflection mirror and an optical path length of a second light beam reflected by the second reflection mirror is set to a coherence length of light output from the light source or less. The imager acquires an interference image in a state in which the cell is placed at a position conjugate to an imaging plane in a first optical system between the imaging plane and the first reflection mirror.

Abstract: An aggregated cell evaluation apparatus includes a laser light source, a speckle image acquisition unit, an SC calculation unit, an evaluation unit, and a memory unit. The speckle image acquisition unit acquires a two-dimensional speckle image by forward scattered light generated in aggregated cells by irradiation of the aggregated cells with laser light output from the laser light source. The SC calculation unit calculates a speckle contrast value Kn of a speckle image In at each time tn, determines a maximum value Kmax among the speckle contrast values K1 to KN, and normalizes the speckle contrast value Kn at each time tn by the maximum value Kmax to obtain a normalized speckle contrast value Kn?. The evaluation unit evaluates motion of the aggregated cells, based on the normalized speckle contrast value Kn? at each time tn.

Abstract: A reception-signal adjusting unit adjusts a waveform of a digital reception signal so that amplitude is equally distributed on a positive side and a negative side. A digital filter unit adds a predetermined delay to an input signal by delay elements serially connected as many as taps, multiplies a delay-added signal from each of the delay elements by a corresponding tap coefficient, adds all signals after the multiplication. A CMA-tap-coefficient estimating unit estimates a tap coefficient using a CMA. A distortion in the waveform of the adjusted reception signal is compensated by repeating processes of the digital filter unit and the CMA-tap-coefficient estimating unit.
