Abstract

A blind spot detector system (10) adapted to the exterior of a vehicle (14) comprising at least one infrared light emitting diode (LED), an infrared photodetector and demodulator, and a microcontroller. The output power of the infrared transmitter is linearly modulated, enabling the blind spot detector (10) to determine the proximity of the detected object (16). The transmitter output is frequency modulated to screen out random infrared radiation that might adversely affect the operation of the infrared photodetector. The system (10) is calibrated to the position of the attached vehicle (14) by linearly increasing the output power of the transmitter until the rear quadrant of vehicle (14) is detected when the transmitter is outputting power at a pre-determined calibration level. During normal operation, an object (16) detected while the transmitted power is greater than a predetermined lower threshold and less than the calibration level will activate a LED indicator on the system housing.
