Abstract
Provided is an imaging technique capable of detecting a focus even in an imaging apparatus of a speckle image. The imaging apparatus includes a coherent light source that irradiates an imaging object with coherent light, an incoherent light source that irradiates the imaging object with incoherent light, a speckle imaging unit that captures a speckle image obtained from scattered light of the imaging object irradiated with the coherent light, a non-speckle imaging unit that captures a non-speckle image obtained from reflected light of the imaging object irradiated with the incoherent light, and a focus detection unit that detects a focus of the speckle imaging unit on the basis of a focal position of the non-speckle imaging unit.
