Miniature Non-MEMS Scanner For Small Size Imaging Systems
The SMALLEST available non-MEMS Resonant Scanner currently on the market was developed by Electro-Optical Products Corp. 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.
EOPC's technology offers 6 mm diameter, 7x7 mm and 12x7 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.
AGC type driver provides:
- both sine wave and TTL level square wave reference signals
- trimpot control to adjust the phase of the reference signals with respect to the position of the mirror or vane. The adjustable range is 180 degrees.
- amplitude adjustment in the range of 20% to 100% of the full amplitude
The low cost SC-3 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 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).
