您好,我想使用激光照明,但是微镜在光机内部,想问一下要怎么才能将微镜拆出来,并不影响其性能,以及控制程序呢

您好!
DMD本身对光源类型并没有要求,但是对波长,光功率,温度等有限制,需要确保芯片工作在其规格允许范围内,比如波长在420-700nm,Array的温度在0-40、70度等。需要注意的是DMD工作需要PMIC和Controller(DLPA2005+DLPC3478)但是其本身支持的是LED驱动。
尽管如此通常客户不会直接使用激光光源,请参考:e2e.ti.com/.../718076
1. It is difficult to create large enough spot to cover complete DMD with overfill (10-15%). The efficiency will be low.
2. Uniformity could be big issue.
3. Such system also have higher speckle because angular diversity is less.
4. Diffraction efficiency could be poor due to a very slow optics (f#).
请问您需要使用激光光源的原因是什么?
