摘要： An imaging apparatus adjusts the polarization directions of irradiation beams (to a diffraction grating) corresponding to first and second beams respectively which have different polarization directions (for example, by adjusting a relative angle formed between light-emitting ends of respective polarization maintaining fibers) so that the spectral characteristics of the irradiation beams at the diffraction grating coincide with each other. Then, the imaging apparatus acquires a tomographic image indicating polarization information for a object based on beams (that come from the diffraction grating for splitting and diffracting a beam from the adjustment unit) corresponding to the first and second beams respectively which have different polarization directions.

摘要： An image acquisition apparatus irradiates light from a light source to an inspection object, obtains a tomographic image of the inspection object on the basis of a combined beam obtained by combining a return beam from the inspection object due to the irradiated light and a reference beam corresponding to the light, and obtains a plane image of the inspection object on the basis of the return beam from the inspection object due to the irradiated light. The apparatus performs a first scanning process to main-scan the irradiated light when the tomographic image is obtained, performs a second scanning process to main-scan the irradiated light at a speed higher than that in the first scanning process when the plane image is obtained, and performs a third scanning process to sub-scan the irradiated light when each of the tomographic image and the plane image is obtained.
