1. The Fourier transform realized by lensless Fourier hologram, and its application to 3-D measurement were studied. The experimental results were presented.

2. The numerical reconstruction of digital lensless Fourier transform holography for microstructures measurement is experimentally shown.

3. For the microscopy by off-axis lensless Fourier transform holography, Fresnel reconstructing method is better than the convolution method.

4. The operation for numerical reconstruction of digital lensless Fourier transform holography is experimentally presented.

5. However, Digital lensless Fourier transform holography has more outstanding strongpoints and better advantages for shape and deformation measurement of microstructures.

6. This lensless intensity correlation system is simple and easy to operate and decreases the requirement of resetting precision for the filter.

7. A new type of holographic sight based on lensless Fourier transform was investigated.

8. For synthetic aperture digital lensless Fourier transform hologram, a screen-division reconstruction method is proposed based on theoretical analysis.

9. Now, if you make a cup very deep and turn the sides over, you eventually make a lensless pinhole camera.

10. In this paper, we propose a method for making a one-step lensless single-ray rainbow hologram, which makes the system structure simpler while the area of hologram larger.

11. The critical part of this sight is a holographic optical elements combined with a lensless Fourier transform hologram and a holographic beam transformer.

12. The main contents are:(1) The recording and numerical reconstruction of lensless Fourier hologram are analyzed by spherical wave theory.

13. Chu Fun, a popular 32-year-old morning-radio host, wears contact lenses for nearsightedness, but she wears glasses, too,(sentencedict.com) choosing from among four pairs of lensless spectacles.
