Therefore, the light sensor generates the sensed image with uniform resolution.

Abstract: A multi-aperture passive light sensor and method for detecting motion and edges of an object are described. The sensor may include at least two focusing lenses mounted on a spherical surface for focusing light from the object into the ends of optical fibers, the optical axis for each lens diverging at an angle from that of adjacent lenses depending on the intended application. Each lens is located closer to the end of its associated optical fiber, which is disposed coaxially to the optical axis of the lens, than the natural focal plane of the lens, thereby blurring the light received from the object. Light exiting the fibers is detected by photosensors located at the opposite end of each optical fiber, and voltage differences between the voltages generated in response to the light intensity impinging on the photosensors are used to detect motion and edges of the object.

Abstract: The current application is directed to autofocus subsystems within optical instruments that continuously monitor the focus of the optical instruments and adjust distances within the optical instrument along the optical axis in order to maintain a precise and stable optical-instrument focus at a particular point or surface on, within, or near a sample.

The described autofocus subsystems employ multiple calibration curves to precisely adjust the z-position of an optical instrument.

Abstract: A laser scanning microscope (LSM) having variable light intensity and a control method for the same. The light intensity of a laser beam in an LSM has been controlled to date with high accuracy, but also high costs by means of an acousto-optic component (AOM, AOTF). According to the invention, such a component for beam modulation is to be omitted, without reducing the exposure accuracy of the sample. In an LSM, a directly modulated laser diode (10) is used with an electric control (12) for direct modulation. Said laser diode (10) has a turn-on delay of the light intensity that is dependent on the amount of the control variable when subjected to an electric control variable. The control (12) is designed such that the fluctuation width (??tV) of the occurring turn-on delay (?tV) is smaller than 1 ?s, particularly smaller than 0.5 ?s. Thus highly exact modulation without an acousto-optic component is possible.
