Measurement principle with ToF camera

A ToF camera measures depth by emitting modulated light, such as a laser, and capturing the light that bounces off an object. The distance can be determined by the time delay Δt between when the light is emitted and when the reflected light is received. The time delay is proportional to twice the distance between camera and object (round trip).

Therefore, the distance can be estimated as depth d = (c × Δt)/2. Here, c is the speed of light. In this way, a ToF camera can be used to measure 2D data and the necessary depth information.

This article introduces the details of Analog Devices' ToF camera module.

ToF camera module that accelerates application development

The analog front-end ADDI9036 from Analog Devices accelerates the development of your ToF camera application.

In addition, CIS Inc. (CIS), an alliance partner of Analog Devices, Inc., offers a ToF camera module DCC-RGBD1 that uses the ADDI9036. An easy-to-understand explanation of the ToF camera module DCC-RGBD1 and its mounted device!

Product features of DCC-RGBD1

CCD ToF Signal Processor ADDI9036 with Programmable Timing and V-Driver

The ADDI9036 is a highly integrated device that integrates an analog front end, a programmable instruction set architecture timing generator, a 7-channel laser diode driver, a 7-channel H-driver, and a 16-channel vertical driver (V-driver) for high precision. It is the best product for ToF CCD cameras.

Since the ADDI9036 is a highly functional product, it requires considerable development resources to fully utilize it. In addition, since ToF camera development also requires specialized know-how, the ToF camera module provided by CIS solves these issues.
