Many optical applications require an off-axis sensor configuration to leave a clear aperture for light transmission through the center of a rotating optical element, which may be a polarizing optic, a micro filter wheel, a wedged prism or other component.
Hall effect position sensors with on-chip analog-to-digital conversion (ADC) lend themselves to very tiny systems. Using a novel implementation of these integrated linear position sensors, engineers at New Scale Technologies created a unique off-axis rotary position sensor that delivers absolute angular position information over a standard I2C serial digital interface. This sensor has a wide clear aperture, very small size and low power use. Coupled with New Scale’s tiny piezoelectric motors, it enables highly-miniaturized optical systems.
Technical paper Presented at Actuator 2012 by David Henderson, New Scale Technologies – Micro-scale smart actuator modules have recently been commercialized for imaging systems. These smart actuators enable “plug and play” integration, rapid prototyping and faster times to market.
Article published in Electronic Products – Technology developed for today’s smart phone cameras is being extended for use in non-consumer applications. In this article we discuss how and why phone camera focus systems evolved from voice coil motors to piezo motion systems, and what that means for designers of embedded imaging systems for non-consumer applications.

We all are familiar with the consumer digital cameras that are in our pockets, mobile phones and personal computers. Thanks to incredible advances in microelectronics, CMOS image sensors and optics, most of us have a very good camera within reach most of the time.
Now these tiny cameras are inspiring product engineers in “non-consumer” applications—such as biometric identification, medical and diagnostic devices, and machine vision—to make even greater products. In fact, markets for these new applications are projected to grow faster than consumer camera markets over the next few years.
In this article we discuss sensor and lens requirements, compare the M3-F focus module to voice coil motors and stepper motors, and talk about image processing, digital signal processing and other system considerations.

Article in Design News – Dramatic reductions in voltage and power requirements are making tiny piezo motors and drive systems an interesting option for portable, low-power medical devices. By eliminating the need for the high voltage normally associated with piezo systems, a new piezo motor design from New Scale Technologies enables miniature motion systems that operate on a single 3-V battery without using voltage boost circuits.
