Abstract: Provided is a compact, low-cost optical measuring apparatus capable of acquiring an image of a target to be measured without moving a mirror or using a wavelength-scanning light source or beam splitter. A laser beam emitted from a light source is split into first and second beams, and the first beam is focused as a signal beam onto the target by a lens for irradiation purposes, while the second beam is reflected as a reference beam by a mirror without irradiating the target.

Then, the detection signals are operated by a signal processing unit. During the measurement, the focus position of the first beam is moved at least in the optical axis direction.

Abstract: To measure a surface state, reflective CARS is suitable in terms of the signal intensity. However, with the reflective CARS, it has been difficult to identify the surface position because the shape information is not acquired. Thus, a reflective CARS microscope is combined with a high-resolution phase sensor. The surface position is identified with the phase sensor, and reflected CARS generated from the surface is detected, so that composition analysis is performed.
