102 light beams sent carry out the micropore of shaping and filtering.For example, microporous element 104 can also
It is provided with the plate-shaped member of micropore.Alternatively, the pore size of micropore can be adjusted manually or automatically, class
It is similar to the iris diaphgram used in such as camera.So, unthreaded hole diameter on the one hand can be adjusted to obtain
Suitably (such as coherence is higher) spot light, on the other hand can control thang-kng amount, and change regards
Wild bright-dark degree.
Reflection part 108 is treated into for reflecting shaped and filtering light beam 106-1 with being incident upon
On picture object 110, and any existing part being capable of reflecting light can be used (for example, plane
Mirror, prism etc.).Alternatively, reflection part 108 can manually or automatically rotate, shaped to change
With the light beam 106-1 of filtering and the object plane where object 110 to be imaged angle, so as to obtain not
