Abstract: An eye-tracking system comprises one or more optical sources configured to emit infrared light with a narrow spectral linewidth toward an eye of a user and one or more shuttered optical sensors configured to receive infrared light reflected off the eye of the user. A controller is configured to pulse the one or more optical sources on and off, such that a pulse-on duration is less than a duration needed to fully thermalize each optical source. The controller is also configured to open the shuttered optical sensor for a detection duration based on the pulse-on duration. A conformation of the user's eye may be indicated based on infrared light received at the shuttered optical sensor during the detection duration.

Abstract: With the object of preventing deterioration of or damage to a photodetector caused by excessive light by more reliably preventing the excessive light from entering the photodetector, a microscope of the present invention is provided with a high-sensitivity detector, such as an HPD, a GaAsP, an EM-CCD or the like, that detects observation light coming from a specimen, a box-shaped casing that has an opening that allows contained items to be placed therein and removed therefrom and that covers the high-sensitivity detector, a door that can close off the opening of the casing, a switch that restricts light detection by the high-sensitivity detector by turning on and off a drive voltage to be applied to the high-sensitivity detector, and an opening restricting mechanism that allows the opening of the casing in the closed state imposed by the door to be opened only when the light detection by the high-sensitivity detector is restricted by the switch.

Abstract: A method of estimating non-linearity in a response of an optical detector comprises emitting optical radiation at different intensities. The method includes, at each intensity: amplitude modulating the emitted optical radiation at a modulating frequency to produce amplitude modulated optical radiation; detecting the amplitude modulated optical radiation with the optical detector to produce a detected waveform; and generating a Fourier transform of the detected waveform that includes a fundamental frequency equal to the modulating frequency and harmonics thereof. The method further includes estimating the non-linearity in the response of the optical detector based on a change in an amplitude of a second harmonic of the fundamental frequency relative to an amplitude of the fundamental frequency across the Fourier transforms corresponding to the different intensities.
