Broadcom offers a wide range of optical sensors solutions including ambient light, RGB color, proximity and gesture sensors.
A wearable device with an optical sensor is disclosed that can be used to recognize gestures of a user wearing the device. Light sources can be positioned on the back or skin-facing side of a wearable device, and an optical sensor can be positioned near the light sources. During operation,...
Application of these optical sensors ranges from computers to motion detectors. For optical sensors to work effectively, they must be the correct type for the application, so that they maintain their sensitivity to the property they measure. Optical sensors are integral parts of many common devices,...
This class of transducers consists of special-purpose vacuum tubes used as optical detectors. They are all relatively large, require a high-voltage power supply to operate, and are used only in very specialized applications (as is true with vacuum tubes in general). These sensors exploit the ph...
METIRIO Encoder: the Smallest Encoder in its Class An optical encoder is a device that produces precise electrical signal outputs that correlate exactly with the linear motion along a guide or the angular displacement of a rotating shaft. The encoder uses optical sensors to interpret carefully distr...
the same number of lasers as sensors is needed to achieve simultaneous read-out. This need for hardware scale-up can be mitigated by tuning all read-out interferometers to the same wavelength as the laser88or by using frequency-modulation schemes that rely on the sinusoidal spectrum of the int...
Active, optical range imaging sensors collect three-dimensional coordinate data from object surfaces and can be useful in a wide variety of automation applications, including shape acquisition, bin picking, assembly, inspection, gaging, robot navigation, medical diagnosis, and cartography. They are uniqu...
(cause blindness) and destroy optical sensors. As a result, the use of lasers in weapons is frequently reported. Aside from irreversible eye damage, certain types of laser illumination may create transitory visual effects, such as distraction, confusion, or discomfort, and create potentially ...
Complementary metal-oxide-semiconductor (CMOS) technology has revolutionized optical imaging by facilitating the development of a new generation of detectors that offer higher framerates compared to their predecessors based on charge-coupled devices1. CMOS sensors are generally compact and cost-effective, ...
Importantly, the present system differs from other displacement sensors in that it does not rely on a motion along the “axis of sensing” in order to detect motion or displacement. On the contrary, the distance from the movable surface being sensed and the fixed sensor remains constant. This...
