I am interested in using an IR receiver (as opposed to a standalone PIN photodiode or phototransistor) to measure distance/range. I thought I had found an appropriate match in Vishay's TSSP4P38 mid-range proximity sensor, which varies its pulse width with reflected signal strength. These, however, seem to only detect changes in distance as stated in p.3 of this document from Vishay; also, it's reflective and I want to be able to detect the distance (and possibly bearing using an array of IR detectors) from an IR emitter as depicted in the image below.
After my search, I have found only Vishay offers an IR receiver capable of outputting "analogue" information; is there an alternative IR receiver capable of measuring absolute distance I have overlooked? I would like to exhaust my IR receiver options first, before I look into using a photodiode/phototransistor which will require extra circuitry, such as amplification, filtering and demodulation.
Additional information: Range of ~2m to 3m and not too sure of accuracy and resolution at this stage, but possibly within ~10cm @ 3m.
