Patent number: 8564761Abstract: A surface shape measuring apparatus includes an illumination system and a light receiving system. The illumination system splits wide-band light from a light source into measurement light and reference light, illuminates the measurement light to obliquely enter a surface of the film, and illuminates the reference light to obliquely enter a reference mirror.
