We developed a pea-sized spectrometer that can obtain the spectral characteristics of mid-infrared light emitted from the human body. The apparatus consists of a compact optical system with two lenses (φ 6 mm) and an optical axis length of 14.65 mm, designed for integration into wearable devices. In addition, the device has a high time resolution that allows it to acquire the spectral characteristics of one line in one frame. In this paper, we describe the principle of the device and the measurement results of a human wrist.
