Miniature Non-MEMS Scanner for Small Size Imaging Systems
The SMALLEST non-MEMS Resonant Scanner currently on the market was developed by Electro-Optical Products Corp. It is a miniature electromagnetically driven moving mirror device (0.9 x 0.5 x 0.4 inches), which deflects a light beam with a continuous sinusoidal motion.
The SC-3’s mirror size is what truly differentiates the product from MEMS-based scanners. A mirror in a MEMS-based scanner is typically 1x1 mm, whereas EOPC’s technology offers 6 mm diameter, 7 x 7 mm and 12 x 7 mm size mirrors, with an optical scanning angle up to 50°, and a fixed-frequency scanning range from 100 to 1000 Hz, fixed at any one value within the range.
A combination of features establish the optical scanner as a suitable component for applications requiring good imaging with minimal distortion. The resonant scanner does not have bearings or moving parts and can run for infinite times without failing.
The scanner requires very little electrical drive power. It operates in a wide temperature range and has good frequency stability and scan repeatability coupled with high flexural stiffness that provides good shock and vibration resistance.
The low cost scanner is an excellent tool to be used in OCT imaging studies and fits emerging trends of building smaller, portable and handheld systems, especially in the medical field, making diagnosis of diseases and treatment of patients more affordable and less expensive.
Resonant scanners are used and can be potentially used in the following sample of applications: Improving Cancer Diagnosis, Ophthalmic Imaging, Adaptive Optics, Optical Coherence Tomography, X-ray Technology, DNA sequencing, Brain Imaging, Detecting Cognitive Recognition, Dentistry, Dermatology, Developmental Biology, NDE/NDT, Oncology and High Resolution Imaging of Optical Coherence Microscopy (OCM).
EOPC manufactures a comprehensive line of standard and custom resonant scanners that can also be used in a raster scanning X,Y system, locked to an external clock or locked in a master / slave mode (all offered by EOPC).
