Abstract: A device for controlling an amount of light of a lighting unit for use in an endoscope, used to view an image of an object. The device includes a light shield for shielding light generated by a light source and transmitted to the endoscope. A stepping motor drives the light shield for a series of predetermined time intervals. Brightness of the image is detected during each of the time intervals and pulses are generated during each of the time intervals. The number of pulses generated is determined in accordance with a difference between the brightness of the image detected during each of the time intervals and a desired brightness of the image. The pulses generated are used to drive the stepping motor in each of the plurality of time intervals.

Abstract: Calculator for determining proper exposure times in making color prints from color negative films comprises an opaque mask with three series of windows having respectively blue, green and red filters of graduated density. The windows have double wedge shape to provide contiguous points and other points remote therefrom. Color print paper is test exposed to light passing through the negative, a diffusion filter, and the graduated filters; when the paper is developed, the correct exposure time is indicated on the paper by the faintest double wedge image which has sharply defined points. A filter device for use in conjunction with the calculator comprises a wheel rotatably mounted on the lens barrel of a projector and having a series of openings: one clear for focusing, one with a diffusion filter for the test exposure, and the others with blue, green, and red filters respectively.

Abstract: A technique of determining the presence of a species in a sample may include passing light through an optical filter. In an example, the optical filter may include a spatially variant microreplicated layer optically coupled to a wavelength selective filter. The wavelength selective filter may have a light incidence angle-dependent optical band. The spatially variant microreplicated layer may be configured to transmit light to a first optical region of the wavelength selective filter at a first predetermined incidence angle and to a second optical region of the wavelength selective filter at a second predetermined incidence angle.

Abstract: A radiation-sensitive device configured to determine an ambient radiation intensity is disclosed. The device includes at least one set of optical filters comprising: a first optical filter having a first passband spanning a portion of a spectrum associated with a radiation-emitting device and a portion of an ambient radiation spectrum; and a second optical filter having a second passband spanning a portion of the spectrum associated with the radiation-emitting device and a portion of the ambient radiation spectrum, the second passband different to the first passband. The device also includes processing circuitry configured to determine, from an intensity of incident radiation sensed using the first and second optical filters and based on the spectrum associated with the radiation-emitting device, a contribution of ambient radiation to the intensity of incident radiation sensed using the first and second optical filters.
