A surgical system includes a first detector that includes a first array of pixels configured to detect light reflected by a surgical instrument and generate a first signal comprising a first dataset representative of a visible image of the surgical instrument. The surgical system also includes a second detector, comprising a second array of pixels configured to detect infrared radiation produced by the surgical instrument during a procedure using the surgical instrument and generate a second signal comprising a second dataset representative of an infrared image of the surgical instrument. The surgical system further includes a processor configured to receive the first and second signals, identify from the first dataset data representative of the surgical instrument, and identify from the second dataset data representative of one or more regions of the surgical instrument above a predetermined threshold temperature. The processor is also configured to generate a modified image of the surgical instrument based on data identified from the first and second dataset. The modified image includes visible indicia in the one or more region of the surgical instrument at or above the predetermined temperature.

A light detection device includes: a Fabry-Perot interference filter provided with a light transmission region; a light detector configured to detect light transmitted through the light transmission region; a package having an opening and accommodating the Fabry-Perot interference filter and the light detector; and a light transmitting unit arranged on an inner surface of the package so as to close an opening, the light transmitting unit including a band pass filter configured to transmit light incident on the light transmission region. When viewed from a direction parallel to the line, an outer edge of the Fabry-Perot interference filter is positioned outside an outer edge of the opening, and an outer edge of the light transmitting unit is positioned outside the outer edge of the Fabry-Perot interference filter.
