A spectral encoder for producing spectrally selected images of a radiation field containing multiple spectral components. An imaging spectrograph defines a first optical path that produces from the input radiation field a spectrally dispersed image comprising multiple spectral components displaced along a dispersion direction. Spectral pass bands are encoded on the dispersed image by a programmable spatial light modulator using one or more spatial masks. The imaging spectrograph further defines a second optical path that reverses the spectral dispersion of the first path and produces a spectrally-encoded polychromatic output image containing only those spectral components encoded by the spatial mask. The first and second optical paths share a common dispersing element. A detector records at least one spatial region of the spectrally encoded output image.

An apparatus, system and method including an ophthalmic lens having an optic with an anterior surface, a posterior surface, and an optical axis. The ophthalmic lens further includes a first region having a first optical power and a second region having a second optical power. The ophthalmic lens further includes a third region having an optical power that progresses from the first optical power to the second optical power. The progression may be uniform or non-uniform. Each of the first, second and progression optical power may include a base power and an optical add power. Each of the first, second and progression regions may provide a first focus, a second focus and a plurality of third foci, respectively.

A demosaicking method and apparatus for color filter array interpolation in digital image acquisition systems is provided. The method includes a data-training phase and a data-practice phase. In the data-training phase of this invention, a huge volume of image samples are received for statistical analysis and compared with their corresponding full-color images. The optimal samples are then recorded in a database. In the data-practice phase of this invention, the images of color filter array are reconstructed. The present invention not only significantly improves the image quality but also reduces undue hardware cost. Furthermore, it has an advantage of ease of hardware implementation. All the color relationships of neighboring pixels are recorded in a database for statistical analysis. The database is not limited to only one set. It is also pretty flexible, and can be adjusted or updated depending on desired applications.

The present disclosure relates to an active energy ray curable inkjet ink for use in a single pass printing inkjet system, the inkjet ink containing a colorant, a monomer and at least one initiator, wherein the sum of the integrated value(s) of absorbance across wavelengths from 380 to 410 nm of the initiator(s) is at least 35, and 0.02≦amount of initiator/amount of monomer≦0.50 (weight ratio) is satisfied. The disclosure also relates to an ink set including the ink. The present disclosure is able to show printed articles that exhibit no wrinkling or tack, excellent color reproducibility, and reduced amounts of residual components within the cured film of printed articles, while offering high productivity, and can also show an active energy ray-curable inkjet ink cured film which has a low residue ratio and is of low-odor, while exhibiting similar print quality and productivity to existing printing systems.

The invention discloses acid-pickling-free hot rolled strip steel with the high surface quality. Oxide layers are arranged on the surface of the acid-pickling-free hot rolled strip steel and comprise the surface oxide layer and the inner oxide layer, wherein the inner oxide layer closely adjoins the surface oxide layer and is located on the inner side of the surface oxide layer. The surface oxide layer comprises a pure iron layer relatively located on the outer layer and a ferric oxide layer relatively located on the inner layer. The appearance and surface quality of the acid-pickling-free hot rolled strip steel approximate to those of a cold-rolled plate, the acid-pickling-free hot rolled strip steel is excellent in formability, and the oxide layers cannot fall in the stamping process. In addition, the invention discloses a manufacturing method of the acid-pickling-free hot rolled strip steel. The method includes the steps of (1) smelting and casting, (2) hot rolling and (3) finishing. According to the step of hot rolling, the heating temperature is 1100-1300 DEG C, heat preservation is conducted for 1-5 h, the final rolling temperature is not smaller than 850 DEG C, the strip steel is cooled at the speed of 1-10 DEG C/s after finish rolling, and a hot-rolled plate is reeled at the temperature of 600-750 DEG C. The acid-pickling-free hot rolled strip steel can be obtained through an existing hot rolling production line, acid pickling is not needed, the cost is low, and the quality is high; and the acid-pickling-free hot rolled strip steel has the application prospects of replacing acid-pickled plates and part of cold-rolled plates.

The present invention relates to a low calorie coffee mix composition with a natural sweet taste prepared by using D-tagatose instead of sugar for a diet or a low calorie coffee mix.
