Abstract: An object of the present invention is to widen a range in which line of sight change is possible, particularly in a pan direction. According to the present invention it is possible to acquire high line of sight changing speed. A pan mirror is capable of rotation in forward and reverse directions about a third rotational axis. Also, the third rotational axis extends in a direction that is substantially parallel to a line of sight direction directed from a tilt direction control section to the pan mirror. An angle ? formed by the pan mirror and the third rotational axis is set in a range 0°<?<90°. The tilt direction control section can scan line of sight direction with respect to a virtual plane formed by a rotation locus of the pan mirror. The tilt direction control section can also control tilt angle of the line of sight direction from the pan mirror to a physical object.

Abstract: An objective cell is irradiated with laser beam of a predetermined wavelength. Only Stokes light is selected out of detected light including reflected light and scattered light of the laser beam, and a Raman scattering spectrum is obtained by dispersion of the selected Stokes light. A transcriptome of the objective cells is estimated, based on the Raman scattering spectrum. It is preferable to estimate the transcriptome of the objective cells, based on N-dimensional Raman data obtained by dimensional reduction of the Raman scattering spectrum. This configuration only needs to irradiate the objective cell with the laser beam and does not require to destroy the objective cell. As a result, this enables the transcriptome of the cell to be estimated in a short time period without destroying the cell.
