Abstract: An approaching apparatus based on spectral shift is disclosed, which includes a broadband light source, an optical-guide unit, and an optical receiving unit. The broadband light source emits a broadband light with the first central wavelength to the optical-guide unit and illuminates a sample via a probe within the optical-guide unit. A generated broadband light of the second central wavelength goes back the optical-guide unit via the original optical path to reach the optical receiving unit. Then, the receiving unit calculates the distance between the probe and the sample based on the characteristic curve of the approaching distance vs. the deviation of the first central wavelength. The deviation is used for feedback control so that the displacement driver moves the probe to adjust the distance between the probe and the sample.

Abstract: The present invention provides an apparatus and method for enhancing image resolution by a position perfurbation modulation which changes optical imaging paths by a rotatable wedge lens turntable. The imaging positions on an image detector is periodically changed so as to obtain the effect of the displacement disturbance and to breach the resolution limitation of the image detector. The present invention could further cooperate with the design of an optical imaging system and image processing to increase the image resolution and detect where a questionable pixel situates.

Abstract: A position micro-perturbation device is disclosed, comprising two wedge-shaped lenses mounted coaxially and rotatable with respect to each other to change the light path of an image and bring about position micro-perturbation. A photodetector is used to pick up the image as a result of the position micro-perturbation, and an image-processing algorithm is further used for calculation. The amount of displacement and direction of the light path of the image is freely adjustable so that the position micro-perturbation can be occurred at any position. Hence, the resolution of the photodetector is high. Furthermore, because fewer wedge-shaped lenses mounted coaxially are used, the size of the position micro-perturbation device, as a whole, can be small and achieved at reasonable cost.
