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 4):
The height detection apparatus according to  claim 1 , wherein\n the control device is configured to execute: a first step of generating a first command value array for specifying a position of the Z stage such that the Z stage moves at a constant speed and a second command value array for specifying brightness of the white light such that brightness of the white light successively changes in the first to K-th levels in accordance with a position of the Z stage; a second step of loading an image captured by the imaging device in a constant cycle while controlling the position of the Z stage and the brightness of the white light based on the first and second command value arrays, and obtaining a number of an image in which luminance of a pixel is highest in a period during which the brightness of the white light is set to the k-th level; a third step of obtaining an envelope of a curve representing a relation between the position of the Z stage and the intensity of the interference light, for each pixel of an image, using the number of the image and luminance of the loaded image, detecting a number of an image in which the envelope is largest, and detecting, as a focus position, the position of the Z stage obtained by converting the number of the obtained image; and a fourth step of obtaining the height of the target object based on the focus position obtained for each pixel of the image.
