Patent ID: 7719760

Claim:
An optical microscope system for detecting nanowires, comprising: a light source for emitting light to provide the light to a nanowire sample; a rotational polarizer provided on a path of the light emitted from the light source for polarizing the light; a polarizer controller electrically coupled to the rotational polarizer for rotating the rotational polarizer at a first frequency; an optical microscope for detecting a nanowire image using the light that is polarized by the rotational polarizer and incident on the nanowire sample; a CCD camera provided in a region of the optical microscope for photographing and storing the nanowire image detected by the optical microscope; and a data processor for selectively extracting only pixels corresponding to the nanowire sample from the nanowire image using Fast Fourier Transform (FFT) and obtaining a new nanowire image, wherein when the light polarized by the rotation of the rotational polarizer is incident on the nanowire sample, intensity of light that is reflected from the nanowire sample is modulated into a second frequency due to the optical anisotropy of the nanowire sample, and the data processor selectively extracts only pixels corresponding to the second frequency from the nanowire image, and obtains a new nanowire image.
