The PPG sensors transmit infra-red waveforms to the skin and detect the signals that are reflected back to the sensor from the skin. The skin partially absorbs the transmitted signals, and the reflected signals are a function of this light absorption, which in turn is a function of the local blood perfusion.

Assessment of venous insufficiency using …
https://pubmed.ncbi.nlm.nih.gov/4061968/
In PPG tracings, a so called "negative segment," which represented a further fall below the baseline after exercising, was often observed. This negative segment is produced by blood flow from the superficial to the deep veins during relaxation, which indicates that PPG can be used to assess the circulatory hemodynamics in the skin.

The PPG (photoplethysmography) Toe Pressure and the related Toe Brachial Index (TBI) are performed to assess the vascular condition of the foot by obtaining systolic pressures at the toe. Toe pressures use an infrared PPG sensor to determine the small vessel vascular condition distal to …
Plethysmography - an overview | ScienceDirect Topics

Photoplethysmography (PPG) uses a small probe that is placed on the calf above the ankle. The probe contains an infrared light-emitting diode and a sensor. The infrared light becomes attenuated by blood in the skin and the arterial pulse wave can be recorded. This technique does not measure volume changes.
ECG vs PPG for Heart Rate Monitoring: Which is Best?
http://neurosky.com/2015/01/ecg-vs-ppg-for-heart-rate-monitoring-which-is-best/
ECG (electrocardiography) sensors measure the bio-potential generated by electrical signals that control the expansion and contraction of heart chambers. PPG (photoplethysmography) sensors use a light-based technology to sense the rate of blood flow as controlled by the heart’s pumping action. Comparison Questions: ECG vs PPG Sensors
