    Graduate IR LED irradiance, radiant exposure and radiance

    Hi! I'm trying to design a device to detect eye blinking while a person is sleeping. I have tried to use TCRT5000 sensor (http://www.vishay.com/docs/83760/tcrt5000.pdf) in the prototype and it works like charm ! However, since the TCRT5000 sensor has an IR emmitter I have some safety...

    Safety of an IR emmitter-phototransistor

    Sorry! The image can not be seen: I need someone to tell me how to compute irradiance (W/m^2), radiant exposure (J/m^2) and radiance (W/(m^2 sr)) using the link about the sensor I provided

    Safety of an IR emmitter-phototransistor

    Hi! I'm part of a team doing an engineering project to design a device to detect eye blinking while a patient in the hospital is sleeping. We have tried to use TCRT5000 sensor (http://www.vishay.com/docs/83760/tcrt5000.pdf) in the prototype and it works like charm ! However, since the...
