From: Temperature field ultrafast detection and identification quantum sensor based on diamond array
a Photoluminescence spectrum (532 nm excitation) of the diamond NV color center. b Simulation results of temperature changes in the center of a diamond (1 × 1 × 0.6 mm³) under conditions where the upper surface is at 100 °C and the remaining five surfaces are at 20°C. c Optical signal detection and data processing response time of the TDI-DQS. d Frequency-swept outputs at different temperatures. e Determination of fixed frequencies and linear ranges. f Relationship between baseline current of the frequency-swept output and temperature. g Relationship between the peak-to-peak current in the frequency-swept output and temperature. h The relationship between dip current of the frequency-swept output and microwave power. i Output response curves under varying microwave power at fixed frequencies
