FCA12776_IRIS-O is an optoelectronic product developed by the Fujitsu semiconductor company. It uses an optical microlens structure to achieve an infrared (IR) reflector, or an optical reflector. The application field for this device is in various industries such as automotive, consumer electronics, healthcare, and industrial automation.

Overview of the technology

The device consists of a single chip that is applied to a thin substrate. It consists of a microlens structure with tiny reflective ridges on the top. The device then uses a series of multiple laser beams to produce an IR-filter effect. This filter is able to reject unwanted reflections and at the same time transmit the desired signal range. The device also comes with a built-in memory, which is used to store the remembered signal pattern. The device finally produces an output signal which is an analog signal with high common-mode rejection.

Working Principle

The FCA12776_IRIS-O works by using an infrared (IR) reflector. This is a device that acts as a low-pass filter in order to eliminate signal or noise from IR sources. The device consists of two parts: an optical microlens structure, and tiny reflective ridges. The optical microlens structure is a series of lenses that are used to concentrate and direct the IR signal onto the tiny reflective ridges. The reflective ridges are then used to filter out the noise while the desired signal is transmitted.

Applications

The FCA12776_IRIS-O can be used in various industries including automotive, consumer electronics, healthcare, and industrial automation. In automotive, the IR reflector can be used to detect objects in the path of a vehicle in order to prevent collisions or accidents. In consumer electronics, the device can be used to detect objects like hands or remotes, in order to control the device. In healthcare, the device can be used to detect skin temperature. In industrial automation, the device can be used to detect the presence or absence of objects being handled by a robotic arm.

Conclusion

The FCA12776_IRIS-O is an optoelectronic device applied on thin substrates which consists of a microlens structure with tiny reflective ridges. It uses multiple laser beams to produce an IR-filter effect which can reject unwanted reflections and transmit desired signals. Furthermore, the device can be used in various industries such as automotive, consumer electronics, healthcare, and industrial automation.
