Visible Light Source Temperature Estimation Using Digital Camera Photography

Light source temperature measurement has been an important aspect in many industrial applications. The aim of this study is to determine the temperature of different sources like flames, incandescent lamps. The sensor installation is difficult in these sources. Imaging these sources to correlate with the temperature is attempted. A digital still camera is used to capture the source images. The ...

Visible Light Communication

The visible light communication (VLC) refers to the communication technology which utilizes the visible light source as a signal transmitter, the air as a transmission medium, and the appropriate photodiode as a signal receiving component. The visible light communication technology has a short history compared with other communication technology, for example, public old telephone service, Ether...

Efficacy of the intense pulsed light source on unwanted hairs

Background: The need for a rapid, non-invasive method for unwanted hair removal has led to the development of various light sources for this purpose. Objective: To evaluate the efficacy of Intense Pulsed Light Source (IPLS) on unwanted hairs. Patients and Methods: In this open, uncontrolled clinical trial, 77 different anatomical areas in 34 referred patients to “Novin Didegan Clinic” in Tehran...
