And in Indirect Incidence, both the IR LED and Photo diode are placed in parallel (side by side), facing both in same direction. In that fashion, when a object is kept in front of IR pair, the IR light gets reflected by the object and gets absorbed by photodiode.
Responsivity in Amps/Watt varies with the wavelength of the incident light, with peak values from 0.4 to 0.7 A/W. The silicon photodiode response is well matched to light sources emitting in the UV to near infrared spectrum, such as HeNe lasers; GaAlAs and GaAs LEDs and laser diodes; and Nd:YAG lasers.
