  • A 3D projection system based on complementary multiband bandpass filter (CMBF) is proposed in this paper, which enables viewers to gain 3D experience through special glasses. Different from the time-multiplex or the spatial-multiplex system, it is a spectrum-multiplex system using pairs of CMBFs. The three pairs of complementary bandpass of a pair of CMBFs can be designed to cover the three spectrum ranges of RGB individually and in each pair the two bandpass nearly do not overlap. In this paper, a 3D projection system is built from two ordinary projectors and its spectrum, brightness and crosstalk have been measured. The average crosstalk is 3%, meeting the basic requirement of crosstalk in 3D display which is less than 10%.

  • Overview: A 3D projection system based on complementary multiband bandpass filter (CMBF) is proposed in this paper, which enables viewers to gain 3D experience through special glasses. Different from the time-multiplex or the spatial-multiplex system, it is a spectrum-multiplex system using pairs of CMBFs. The three pairs of complementary bandpass of a pair of CMBFs can be designed to cover the three spectrum ranges of RGB individually and in each pair the two bandpass nearly do not overlap. By using the CMBFs, the images from left and right projectors can be divided in spectrum as well. The special glass's lens is same as the corresponding CMBFs appended to the projector. So, the left image can only be seen by the left eye through the special glasses and vice verse. In this paper, pairs of CMBFs which can meet the principle of spectrum-multiplex system are made and a whole 3D projection system is built from two ordinary projectors. This 3D projection system does not need special screen which is common in a commercial cinema. That's to say, by adding several CMBF films, common projection system can be adapted in to a 3D one. The system's spectrum, chromaticity, brightness and crosstalk are also measured in this paper. The spectrum is close to the ideal one, only having a few overlaps which will result in the crosstalk. There are some differences in the chromaticity diagrams between the two CMBFs, which will cause a little chromaticity aberration. This problem can be solved by using FPGA to adjust the input digital images to make the triangle in one chromaticity diagram almost the same as the other one. The brightness is over 110 nits when a pure white image is shown and the brightness is below 4 nits when a pure black image is shown. The left crosstalk is less than 2% and the right crosstalk is less than 3.5%. So the average crosstalk of this system is about 3%, meeting the basic requirement of crosstalk in 3D display which is commonly less than 10%. But the crosstalk of 3D projection in cinema is usually less than 2%. To meet this requirement, an improvement in CMBF's overlap must be done in the future, such as making a better pair of CMBFs without overlaps in spectrum. Besides, the brightness and color are not good enough in this system but can be improved easily for the reason that the screen in our experiment is just a wall.
