Brief Introduction

The SCD4101 is a handheld ultrasonic acoustic

imager that usesa 138-element MEMS microphone

array and beamformingtechnology to capture

sound source distribution data.

It simultaneously records real-time video via a

high-definitioncamera and fuses the sound source

distribution map with thevideo feed to dynamically

visualize changing sound sources onthe display.

Portable and lightweight with intuitive operation,

it enables usersto start testing quickly by simply

adjusting parameters such asfrequency range and

dynamic range to meet different

testingrequirements.

It supports photo and video capture, as well as

expandable high-capacity TF cards for fast data

export and in-depth analysis.
