The resolution of image frame can further be promoted.In this present embodiment, two adjacent mirrored sides S2 can be treated as to such as Fig. 4
One mirrored sides S21 is different from the angle that the second mirrored sides S22 favours the first bottom surface S11 respectively, therefore equally can be by
The rotation of mirrored sides S2 and on reflected image light beam L2 at least two different locations of light inputting end 132, and it is described at least neither
It is different from least two different locations generated by rotation with position.In this way, which the parsing of image frame can be promoted further
Degree.In the present embodiment, the resolution that the resolution of generated image frame compares traditional image frame promotes four times.
Fig. 6 is the schematic diagram of the bare engine module of another embodiment of the utility model.Referring to FIG. 6, the ray machine of the present embodiment
Module 100C is similar to the bare engine module 100 of Fig. 2.The two the difference is that, in the present embodiment, bare engine module 100C's is anti-
Injection device 120C includes reflecting element 128 without column reflecting element (see the column reflecting element 124 of such as Fig. 2).Reflection
Element 128 is sheathed in shaft 122.Specifically, reflecting element 128 is including at least one first reflector plate 128_1 and at least
One second reflector plate 128_2, wherein the first reflector plate 128_1 favours the angle of shaft 122 and the second reflector plate 128_2 inclines
