Abstract: In one embodiment, a flow cytometer is disclosed having a compact light detection module. The compact light detection module includes an image array with a transparent block, a plurality of micro-mirrors in a row coupled to a first side of the transparent block, and a plurality of filters in a row coupled to a second side of the transparent block opposite the first side. Each of the plurality of filters reflects light to one of the plurality of micro-mirrors and passes light of a differing wavelength range and each of the plurality of micro-mirrors reflects light to one of the plurality of filters, such that incident light into the image array zigzags back and forth between consecutive filters of the plurality of filters and consecutive micro-mirrors of the plurality of micro-mirrors. A radius of curvature of each of the plurality of micro-mirrors images the fiber aperture onto the odd filters and collimates the light beam on the even filters.

Abstract: A display that can play dynamic video imagery using purely infrared light. Such dynamic video imagery is useful in testing infrared detection equipment. The display contains thousands of solid state infrared LEDs. Different infrared LED types are used. Each type of LED in use emits infrared light in some selected band of the infrared spectrum. The overall display can be designed to simulate infrared signal sources for a particular type of infrared detection system. If a particular infrared detection system detects infrared energy only in a specific range, the infrared LED display can be made to have a high resolution of LEDs within that specific range and a lower resolution of LEDs outside that specific range that would be useful for calibration purposes.

Abstract: An illustrative optical measurement system includes a light source configured to emit a light pulse directed at a target. The optical measurement system further includes a control circuit configured to drive the light source with a current pulse comprising a non-linear rise, and a decline from a maximum output to zero having a duration within a threshold percentage of a total pulse duration of the current pulse.

Abstract: For calculating an optical sensor's regular-discharge probability, a light detection system includes the optical sensor, an application voltage generating circuit for applying a drive pulse voltage to the optical sensor, a discharge determining portion for detecting the optical sensor's discharge, a first discharge probability calculating portion, a sensitivity parameter storing portion for storing the optical sensor's sensitivity parameters, and a second discharge probability calculating portion for calculating a discharge probability of the optical sensor's regular discharge. The first discharge probability calculating portion calculates a discharge probability in: a first state in which light from an additional light source having a known light quantity is incident on the optical sensor or the additional light source is turned off; and a second state in which the additional light source's turning-on/turning-off status is different from the first state, with the drive pulse voltage's pulse width being the same as the first state.
