INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, PROGRAM, AND CELL OBSERVATION SYSTEM

WIPO Patent Application WO/2019/012796

A1

An information processing device according to an embodiment of the present invention comprises a calculation unit and an amplitude replacement unit. The calculation unit repeatedly executes: first light propagation calculation for propagating, from the sensor surface of an image sensor to a support surface supporting a cell to be observed, a first complex amplitude distribution including the light intensity distribution of a hologram of the cell that has been obtained at the sensor surface; and second light propagation calculation for propagating a second complex amplitude distribution obtained as a result of the first light propagation calculation from the support surface to the sensor surface. In the second light propagation calculation, the amplitude replacement unit replaces an amplitude component in the second complex amplitude distribution with a prescribed representative amplitude value at least once.
