A pyrometer holder is mounted to an outer wall of a chamber while holding a lower radiation thermometer. The front end of the lower radiation thermometer is brought into abutment with a mounting portion of the pyrometer holder, and a bottom plate is brought into abutment with the rear end of the lower radiation thermometer. A tension spring is tensioned between the bottom plate and the mounting portion to prevent the lower radiation thermometer from falling off or misregistration. An angle adjusting mechanism adjusts the angle of the radiation thermometer with respect to the outer wall of the chamber, with the front end of the radiation thermometer serving as a supporting point. Thus, the measurement position of the lower radiation thermometer is adjusted.

The ranging device is coupled to the controller. The transmission device loads the ranging device and is coupled to the controller. The controller controls the motion of the transmission device in accordance with the offset distance to correct the offset angle between the ranging device and the object corresponding to the main heat source. After correcting the offset angle, the ranging device detects a first distance to the object by transmitting energy and receiving reflected energy.

The micromechanical photothermal spectroscopy system and method includes a cantilever assembly having at least one cantilever thermal sensor extending from a support. The sensors may be simple bimetallic sensors, or may include microchannels made from two materials having different thermal expansion coefficients for analysis of microfluids. A beam of infrared light is separated out from solar radiation by gratings and filters, and is at least partially projected on the cantilever sensor(s). Heat released from the analyte by absorbance of infrared light results in deflection of the cantilever sensor(s), which is measured by a deflection detector. A filter wheel permits tuning of the sunlight-based infrared light beam to plot a spectrum of absorbance as a function of wavelength or wave number characteristic of the analyte. The deflection detector may be optical (using a laser and position sensitive detector(s)), or may use piezo-resistive material embedded in the sensor(s).
