  • Publication number: 20130335829
    Abstract: A bi-telecentric interferometer continuous zoom imaging device, wherein a collimation object lens set, a telecentric imaging module, a telecentric continuous zoom module, and a CCD of modular design are formed on an integral circular tube main body, and can be calibrated and positioned separately. Then, a multi-partition isolation design is used to partition a housing into independent space for said various modules, to facilitate maintenance and also achieve customization. Collimation object lens set converts parallel light beams of interference pattern into a convergent light beam, and guides it to an imaging route through optical route adjusting means. Then, telecentric imaging module converts interference pattern on imaging route into an telecentric image parallel to optical axis, and telecentric continuous zoom module adjusts a magnifying ratio of telecentric image, then outputs an object image to form it on CCD, thus improving optical distortion and inferior resolution of the prior art.

  • Publication number: 20130308199
    Abstract: A bi-telecentric continuous zoom imaging device, comprising: a collimation object lens set, to convert parallel light beams of interference patterns into a convergent light beam, and to guide it onto an imaging route through optical route adjusting means. A telecentric imaging module converts interference pattern on imaging route into a telecentric image paralleling to an optical axis. Then, a bi-telecentric continuous zoom module adjusts a magnification ratio of telecentric image, and then outputs an object image. Finally, object image is formed on a charge coupled device (CCD). Through application of bi-telecentric continuous zoom imaging device, deficiency of conventional measurement system can be improved, even if the object distance is changed the magnification ratio of image can be kept, minimum optical distortion and good resolution can also be maintained.

  • Patent number: 6844121
    Abstract: A method of manufacturing color filter comprising the steps of forming a metal layer and a photoresistor layer on a substrate; defining a dent over the photoresistor layer and removing the metal layer below the dent; depositing an optical filter material over the resulting structure at relative high temperature, lift off the photoresistor layer by etching the metal layer. The optical filter material can be fabricated at higher temperature (300-400° C.) than conventional cold process, the extinction ratio of the filter made by the optical filter material can be as high as 90% to enhance the performance of the projector system.

  • Patent number: 6768553
    Abstract: The present invention provides a continuous-zoom imaging device of an interferometer. Reflected lights of a reference plane and a test plane interfere with each other to generate an interference pattern. A collimation device converts a parallel light of the interference pattern into a convergent light. An optical path adjustment means guides the light to a polarizing beam splitter. A continuous-zoom device adjusts the magnification ratio of the interference pattern on the imaging passageway and to output an object image, which is then imaged on a charge-coupled device. The present invention can improve the quality of the interference pattern without using any rotating diffuser, and thus has the characteristics of reduced number of components, lowered cost, and shrunk volume. Besides, the present invention can utilize a joint device to connect the continuous-zoom device and an attenuator so as to achieve automatic light adjustment and convenient operation.
