An infrared photothermal beam deflection fourier transform spectrometer
M.J.D. Low,M. Lacroix +1 more
TL;DR: In this paper, a photothermal Fourier transform spectrometer built to accommodate a beam deflection detection system is described, which can also function as conventional absorption FT spectrometers, and also a conventional FT photoacoustic Spectrometer, covering the 3950−450 cm−1 range.

Infrared Photothermal Beam Deflection Fourier Transform Spectroscopy of Solids
TL;DR: In this paper, a Fourier transform spectrometer built with a photothermal beam deflection detector was used to record infrared spectra of organic and inorganic solids, and the total absence of sample-containing devices makes it possible to examine portions of the surfaces of objects which are very large in size.

Thermo‐optical spectroscopy: Detection by the ’’mirage effect’’
TL;DR: In this paper, a new thermo-optical method based on the sensitive detection of thermal gradients adjacent to heated sample surfaces is described, and room and low-temperature experiments are performed using this technique, and its advantages over different methods are discussed.
