Abstract:
1. A method for providing a plurality of magnified images of a device, the method comprising the steps of: illuminating the device with a light having a first wavelength; adjusting a depth of field of an image of the device based on the first wavelength of the light; splitting the image of the device into a first plurality of images based on the first wavelength of the light; magnifying the first plurality of images based on the first wavelength of the light to produce a respective plurality of first magnified images; filtering the plurality of first magnified images based on the first wavelength of the light; providing a filtered first magnified image to an optical detector; illuminating the device with a light having a second wavelength; adjusting the depth of field of the image of the device based on the second wavelength of the light; splitting an image of the device into a second plurality of images based on the second wavelength of the light; magnifying the second plurality of images based on the second wavelength of the light to produce a respective plurality of second magnified images; filtering the plurality of second magnified images based on the second wavelength of the light; and providing a single filtered second magnified image to the optical detector.
