Abstract: The invention provides an infrared detection device (1), comprising an encapsulation housing (2), a main infrared detector (3) and a secondary infrared detector (4) arranged inside the encapsulation housing (2), a temperature sensor (5) and a control unit (6). The control unit is configured to receive data from the main infrared detector (3), the secondary infrared detector (4) and the temperature sensor (5), and configured to provide an infrared measurement from the obtained data. The encapsulation housing (2) comprises at least an opening structure (7, 7a, 7b, 7c, 7d) intended to allow infrared radiation to enter the detection device (1). The opening structure (7, 7a, 7b, 7c, 7d) is covered by a filter (8) which has a mean transmittance value in a first electromagnetic wavelength range greater than the mean transmittance value outside this first electromagnetic wavelength range. The secondary infrared detector (4) has a treatment which provides a different absorptance in the first electromagnetic wavelength range than the absorptance of the main infrared detector (3) in the first electromagnetic wavelength range, being both absorptances higher than zero.

Abstract: The present disclosure provides an optical detection device and an optical path calibration method. The optical detection device includes: a housing 110, a beamsplitter pathway 120, a first photosensor 130, a second photosensor 132, and a calibration light source 134. An aperture 112 is arranged in the housing 110, and is configured to receive radiated light from an external detection region by the aperture 112. The housing 110 processes radiated light from the aperture 112 through the beamsplitter pathway 120, the first photosensor 130, and the second photosensor 132. The calibration light source 134 is arranged inside the housing 110, is configured to radiate calibration light to the beamsplitter pathway 120, and radiate the calibration light to the external detection region through the aperture 112 in the housing 110. The calibration light from the calibration light source 134 and the radiated light from the external detection region are coaxial.
