    Abstract: An optical filter includes a substrate, an adhesion layer formed on the substrate, and a matching composite layer formed on the adhesion layer and including a plurality of first refraction layers, a plurality of second refraction layers, and a plurality of third refraction layers. A quantity of the second refraction layers is less than that of the first refraction layers, and is less than that of the third refraction layers. A refractive index of the first refraction layer is greater than that of the adhesion layer. A refractive index of the second refraction layer is greater than that of the first refraction layer, and is less than that of the third refraction layer. Two of the second refraction layers sandwich one of the first refraction layers therebetween, and are sandwiched between two of the third refraction layers, so as to be jointly defined as a bidirectional incremental module.

    Abstract: Apparatus for producing energy pulses of a sufficiently short duration that only a restricted zone of the target image is illuminated at any given instant. A gating apparatus is adapted to admit to a receiving apparatus a sequence of images from the target subject, each of which images corresponds to a different zone of the target subject. The receiving apparatus is coupled to a recording device that presents to the viewer a threedimensional image of the target subject and that stores the image data for subsequent presentation. Several variations of the three-dimensional data acquisition and display devices are disclosed.

    Abstract: Provided is a filter lens and a method for preparing the filter lens. The filter lens includes a copper complex, wherein the copper complex is formed from a copper compound providing copper ions, phosphoric acid represented by formula 1 herein, and at least one phosphorus-containing compound represented by formulas 2 to 4 herein, wherein the OD value of the filter lens for the incident light wavelength of 930 nm to 950 nm is greater than 4. The present disclosure enables a filter lens to have the function of filtering out near-infrared instead of using a traditional filter component and thus the size of the assembled optical lens module is reduced. The filter lens can further filter out light having other specific wavelengths, and thereby the number of lenses in the assembled optical lens module is reduced.
