A speckle structured light laser is an integrated laser module composed of laser chip, driving circuit and DOE (Diffractive Optical Element). It diffracts single laser beam into millions of fixed, pseudo-random speckle dots via special DOE optics and projects unique granular speckle patterns onto target surfaces.
3D printing defect detection is a quality control procedure to find abnormal flaws during or after additive manufacturing, aiming to eliminate unqualified parts caused by layer shifting, missing printing, air pores, surface pits, warpage, unfused powder and dimensional deviation.
In biomedical laboratories, flow cytometers can analyze dozens of characteristics of individual cells simultaneously at a rate of tens of thousands of cells per second, covering everything from the identifying markers of immune cells to the special functions of stem cells and intracellular signal fluctuations. What gives this screening tool its precise detection capabilities is the "laser team" behind it. Different wavelengths of laser light act like different bands of illumination, precisely lighting up corresponding fluorescent dyes, leaving no secret of the cell hidden.
