Here, we propose a high-resolution, full-field thickness measurement technique utilizing the evanescent fields of high-order cavity modes in microsphere resonators. By exploiting the discrepancy in sensitivity among different modes, this method directly achieves consistent thickness measurements across extensive lateral dimensions without requiring reference surfaces. Compared to other optical methods, it offers a simple design and efficient readout, while maintaining a precision of about 0.10 nm per nanometer of spectral shift.
