Abstract:
A height detection apparatus successively changes the brightness of white light from a first level to a second level in accordance with a position of a Z stage and captures an image of interference light while moving a two-beam interference objective lens relative to a paste film in an optical axis direction, detects, as a focus position, a position of the Z stage where the intensity of interference light is highest in a period during which the brightness of white light is set to the first or second level, for each pixel of the captured image, and obtains the height of the paste film based on a detection result.

Claim (Index 8):
A coating apparatus configured to apply a liquid material on a surface of a target object, the coating apparatus comprising:\n a coating unit having a coating needle to apply the liquid material adhering to a tip end of the coating needle to a surface of the target object; a head including\n a light source configured to emit white light, \n a two-beam interference objective lens configured to divide white light emitted from the light source into two light beams, apply one of the light beams to the target object and the other beam light to a reference surface, and cause interference between reflected light from a surface of the target object and reflected light from the reference surface to obtain interference light, \n an observation optical system configured to observe interference light obtained by the two-beam interference objective lens, and \n an imaging device configured to capture an image of an interference pattern produced by the interference light through the observation optical system; \n a Z stage configured to move the two-beam interference objective lens relative to the target object in an optical axis direction; a positioning device configured to move the head and the target object relative to each other to position the head to a desired position above a surface of the target object; and a control device configured to control the light source, the imaging device, and the Z stage to obtain a height of the target object.
