Optical Sensors - Ambient Light, IR, UV Sensors

The BPDV2150RM-VF-FP is a type of optical sensor used in ambient light, infrared, and ultraviolet sensing applications. It is an integrated four-channel surface mount device that combines four integrated photodiodes (PDs) and four independent signal channels, each containing a variable gain amplifier (VGA) and a low-frequency band-pass filter (BPF) for increased signal-to-noise ratio (SNR).

Advantages

The device offers several features that provide the following advantages:

• High integration
• Low power consumption
• High noise immunity
• High light responsivity
• High signal-to-noise ratio

Application

The BPDV2150RM-VF-FP can be used in various applications such as:

• Ambient light sensing (ALS)
• Infrared thermal imaging
• Light detection and ranging (LIDAR)
• Machine vision
• Robotic navigation
• Remote sensing in areas such as space exploration, military, and surveillance
• Automotive safety systems such as driver assistance systems (DAS) and automated emergency braking (AEB)
• Medical applications such as optical biometric recognition and non-invasive imaging

The BPDV2150RM-VF-FP is ideal for applications that require low power consumption, high responsivity, and high signal-to-noise ratio.

Working Principle

The BPDV2150RM-VF-FP consists of four integrated photodiodes and four independent signal channels. Each channel contains a variable gain amplifier (VGA) and a low-frequency band-pass filter (BPF) for increased signal-to-noise ratio (SNR).When light strikes the photodiode, it generates photocurrents, which is an electrical current generated when the photodiode is exposed to light. The variable gain amplifier (VGA) then amplifies the photocurrents. The amplifier has a gain that is set by the user.The signal is then filtered through the low-frequency band-pass filter (BPF). This filter removes frequencies outside of the range specified by the user, which increases SNR. The signals are then sent to the pins on the device.The device is ideal for applications that need high responsivity, low power consumption, and a high SNR. It is capable of detecting faint light signals in ambient light, infrared, and ultraviolet applications.
